Felipe Montanez: Diligence and Dedication

By James Florence, Diamond Certified Program Reporter

PETALUMA — Years ago, Felipe Montanez was working in a tire shop and ready for a change of pace, so when he came across an advertisement for a career in pest management, he was immediately intrigued. “In particular, I was drawn by the increased independence and sense of ownership that came from taking care of people’s homes,” he says. Within just a few years of entering the field, Felipe progressed from the ground floor to upper management—a streamlined trajectory he attributes to due diligence. “At every step of the way, I just took the initiative to learn and do as much as I could, so when opportunities presented themselves, I was in a position to take advantage of them. I definitely feel like I’ve earned it.”

Today, as operations manager of Hydrex Pest Control of the North Bay, Inc., Felipe says his favorite part of his job is interacting with customers. “One thing I really enjoy is filling in when one of our technicians is out, because it gives me a chance to be in the field and talk face-to-face with our customers. When I ask how their service has been, they typically respond with glowing reviews, which makes me proud of our team.”

Originally from Washington, Felipe came to the Bay Area on a wine tasting excursion and liked it so much that he decided to permanently relocate. Today, as a resident of Rohnert Park, Felipe says he continues to enjoy all that the North Bay has to offer, including good wine, open spaces and scenic views.

Outside of work, Felipe spends much of his time with his wife, Linda, and their two-year-old son, Braydon. Additionally, he enjoys following his favorite Bay Area sports team, the Oakland Raiders. “As a Raiders season ticket holder, I’m very invested in the team, so it’s a big deal for me.”

In his life and career, Felipe espouses the importance of intense dedication. “When I was in the Air Force, my squadron had a saying: ‘Motivated, dedicated, can’t be stopped.’ That’s stuck with me ever since, and I’ve applied it in both life and work. Basically, in any task or goal that I undertake, I fully invest myself and strive to perform to the best of my ability.”

When asked the first thing he’d do if he could retire tomorrow, Felipe says he’d head to an exotic destination. “I haven’t thought a lot about retirement, but if I were to retire tomorrow, I would probably surprise my wife with a trip somewhere. She’s a big fan of Thailand, so I’d take her there on vacation.”

Richard Estrada: Getting the Bugs Out

By James Florence, Diamond Certified Resource Reporter

NOVATO – When Richard Estrada first started working in the pest control industry, he was at a crossroads: burned out, overtired and looking for change. “I was delivering produce for a company based in San Francisco, which meant a lot of very early mornings,” he recalls. “I had just become a father a couple years earlier, and I found I wasn’t able to spend as much time with my son as I wanted because I was always trying to catch up on sleep.”

Richard knew he wanted to transition to a job with regular daytime hours, but he wasn’t sure where to start looking, so when he got an invitation from a friend to try his hand in a totally new industry, he didn’t hesitate to accept. “A good friend of mine owned a pest control company, and he invited me to work with him for a day to see if it was something I’d like to do,” he explains. “As it turned out, I found it very interesting and decided to keep working for him. Sixteen years later, I’m president of ATCO Pest Control.”

Born in East Los Angeles and raised in Iowa, Richard moved to the Bay Area in 1989, where he still lives with his wife, Stella, and their two sons, Nathan and Marcus. After nearly 25 years, he says he still appreciates the natural beauty of the indigenous landscape. “We have the bay, the mountains and so much more. I couldn’t imagine living anywhere else at this point.” Richard and his family like to take advantage of all the area has to offer, engaging in a variety of outdoor activities such as biking, hiking and skiing. One pastime that Richard especially enjoys is golfing with his sons. “My boys and I go golfing quite often. It’s a great way for us to enjoy the beauty of creation and spend some time together.”

In his professional career, Richard says a crucial ingredient for success has been his personal associations. “When I went into business for myself, I knew it would be important to surround myself with people who were smarter than me when it came to business matters. Today, whether it’s industry colleagues or company employees, I continue to partner with people whom I can collaborate with and learn from.”

When asked the first thing he’d do if he could retire tomorrow, Richard says it wouldn’t be a likely scenario. “Quite honestly, I can’t see myself retiring. I enjoy what I do and love working alongside my team members. I might travel and play golf a little more often, but I could never see myself fully retired.”

Q: What were you most known for in high school?
A: My smile.

Q: Which super power would you choose, flight or invisibility?
A: Invisibility.

Q: If you were an insect, what would you be?
A: I think I would be an ant—they’re hard workers and they don’t need to be told what to do.

Q: Do you have any memorable job stories?
A: One time, I got a call about an ant problem at a client’s house. As we were in the kitchen looking at the infestation, the client brought my attention to an ant farm that was sitting on the countertop. We both had to laugh at the irony.

Q: What’s one movie that people would be surprised you’ve never seen?
A: “Arachnophobia.”

What To Ask In Person
Questions to Ask When Meeting with a Representatives of Marin County Pest Control Services in Person

After you have interviewed several Marin County pest control companies by telephone, it’s time to meet with a few in person. You may do this in their offices, or they may want to come into your home or cropland to see the pest problem. You should not feel compelled to have anyone in your home if you are not comfortable; therefore, you may want to consider meeting in their offices first and arranging a walk-through by appointment during a time when you will be home with someone. Always go with whatever is most comfortable for you.

When meeting with a company in person, there are some questions you should ask regarding their services:

General Questions to Ask Exterminators and Pest Control Services:

  • To ensure accuracy, what process do you follow prior to giving estimates for pest control services?
  • What if my pest problem is more severe than originally thought?
  • How soon can you start my pest control treatments?
  • Once you start treatment, how long will it take to complete?
  • Is there a drying time for any wet chemicals?
  • Will clean up afterwards be required? If so, am I responsible for that?
  • Will there be any lingering odors?
  • Do I need to move out of my home while you work?
  • How long will I need to stay out of the area?
  • Is the work warranted? If so, for how long?
  • What does the warranty entail and is it a written warranty?
  • Will I need to wash all surfaces and dishes, etc. before using them after you have applied treatment?
  • Will repeat extermination treatments be necessary?
  • If the problem doesn’t go away after you have completed treatment, will I be charged for you to come back and do it again?
  • Are you insured and/or bonded? (Ask to see a certificate of insurance and find out if the company carries complete insurance coverage with adequate coverage that includes an “errors and omissions” clause that covers accidents like inadvertent staining on carpets or breakage of items.)

If the Pest Problem is a Crop Issue:

  • Will this harm my crops?
  • What precautions need to be taken when picking crops?
  • Will the residue remain on the crops, and if so, for how long?
  • What if it rains right after you apply the treatment?
  • Can I enter my fields right away, or do I need to wait for a certain period of time?

If the Pest Problem is a Rodent Infestation:

  • I have pets. What precautions do I need to take?
  • What treatments will you use to get rid of rodents?
  • What can be done to prevent them from coming back?

  • What To Ask References
    Learn from Previous Pest Control Customers in Marin County

    It’s best to choose a Diamond Certified pest control company because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a pest control company in Marin County, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified pest control company within reach, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your pest control company. Keep in mind, though, that references provided to you by the pest control company are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

    If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

    Questions to ask References of Local Pest Control Services in Marin County

    1. What type of extermination or pest control services did this company provide for you?
    2. Did they do a thorough assessment of your problem?
    3. Were the employees of this Marin pest control company courteous and helpful?
    4. Were you pleased with the work they did for you and the length of time it took to complete the work?
    5. Were you satisfied with the work from this Marin County pest control company?
    6. Was the work completed in a timely manner?
    7. Did the Marin exterminators explain clearly what they were going to do so you could ask questions?
    8. Did they provide you with pest control options?
    9. Do you feel the price was fair for the work that was done?
    10. If you needed this type of service again, would you use this Marin County pest control company again?
    11. Would you recommend this company to others who have experienced pest infestation issues?

  • How To Work With
    Before You Hire a Local Pest Extermination Company

    Pest control can involve hazardous substances that can be harmful to you, your family, and your pets. Before you hire a pest control company, you will want to find out what safety precautions they take when working with possibly hazardous materials, and what you will need to do prior to them coming into your home, and what precautions need to be taken after they are finished.

    Once you hire a pest control company, whether in San Rafael, Novato, Mill Valley, San Anselmo, Larkspur, Corte Madera, Tiburon, Sausalito, Fairfax, Ross, Belvedere or one of the surrounding towns, it will be important to maintain contact with the pest control company to ensure everything is going according to plan and no problems have come up in the process, such as there being a larger infestation than originally thought.

    Sign a Contract with the Pest Control Company
    When you are satisfied with the information your Marin County pest control company has given you, and you are ready to begin, you should sign a contract that includes a warranty for the work to be done. Any changes to the contract should be completed in writing. Do not give a verbal agreement for anything without having it put into writing and signed by both you and the company.

    Some things to look for in a pest control contract are:

    • Possible exclusion clauses in the contract. Exclusion clauses specify the things that can cause the contract to be canceled.
    • Is there an arbitration clause or other method to settle possible disputes?
    • Can either you or the pest control company cancel? Will there be penalties assessed if you cancel the contract?
    • The contract should be signed by both parties.

  • Be a Good Customer
    How Can You Be a Good Pest Control Company Customer?

    It’s the pest control company’s responsibility to ensure they are meeting all safety and quality pest control standards when working in your home or on your land, but you play a big part in the success of the work. Here are a few simple steps you can take to be a good customer when hiring a Marin County pest control company.

    • Remember, a friendly smile goes a long way!
    • Be clear and upfront with the pest control company. Let them know what you want from your pest control company, the long-term outcome you’re expecting and specific ways they can satisfy your expectations.
    • Before you hire a pest control company in Marin County, restate your expectations and goals, and reiterate to the pest control company representative your understanding of the agreement. Most problems with local pest control companies occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.
    • Ask your pest control company representative if you should call to check on the progress or if he will call you with updates.
    • Be sure your service representative has a phone number where they can reach you at all times while they’re working in your home or fields. The work will move along more smoothly if your pest control company can reach you for any necessary updates, questions or work authorizations.
    • When the company calls you, return calls promptly to keep the treatment process on schedule.
    • Pay for the pest control company work promptly.

    Why would you want to be a good customer? Pest control companies in Marin County appreciate customers who are straightforward, honest, and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship. Things may very well go smoother and any problems may be more easily resolved.

Check The Work
Check the Work Done Against the Invoice

Upon the completion of the treatment in your home, you will want to sit down with the Marin County pest control company representative and go over the invoice and the work completed. Have the pest control worker explain clearly the work that was done, and any follow up work that needs to be done by the company or by you. Make sure you have a clear picture of what has been done in your home, or on your land, so that, should the problem arise again, you will be able to communicate with the company clearly regarding what was done and what may still need to be done. Additionally, obtain an accurate list of any chemicals that were used in case you or someone in your home has a reaction to them.

Finally, review all work completed with what is on the invoice you receive from the pest control company to ensure all work being paid for was actually done, and that all work was done to your satisfaction.

Top 10 Requests
Extermination Service Requests Made of Marin County Pest Control Services

There are many reasons why someone may need a pest control company in San Rafael, Novato, Mill Valley, San Anselmo, Larkspur, Corte Madera, Tiburon, Sausalito, Fairfax, Ross, Belvedere, and the surrounding towns. The most common reasons someone would contact a pest control company in Marin County are:

Ant Control
Ants will come into a home if there is a food source. Many times you will see a line of ants marching single file across your countertop or floor to or from a food source. What is the food source? Will removing it get rid of the ant problem? Can you locate and plug the hole they use? If the ants have built a colony somewhere within your home, the issue could be bigger than you think.

Bat Control and Bat Removal
In many states bats are a protected species, but bats can cause serious problems if they are in your home. First and foremost, bats can carry rabies. If someone is bitten by a bat, there is a high likelihood of needing rabies shots, especially if it is unknown if the animal is a carrier of rabies. Better safe than sorry is the view of most people as rabies is a very serious disease that has no known cure. Additionally, bat droppings (guano) can harbor bacteria and the fungus known to cause Histoplasmosis, and be a food source for other pests, such as roaches. If you have bats in your home, it is best to consult a professional regarding the removal and cleanup of the infested space as special equipment and suits may be needed depending on the amount of guano.

Bed Bugs
Bed bugs can be a serious problem, and there has been a recent escalation in infestations. If you suspect you have a bed bug problem, you will want to seek help immediately to get the problem under control.

Bees/Wasps/Hornets/Yellow Jackets
Bees can be beneficial to crops, but some types of bees, such as carpenter bees, can cause damage to your home. Also, wasps, hornets, and yellow jackets can be aggressive when defending their home territory. If someone in your home is allergic to bee stings, this can be a serious problem. Whether you want the creatures moved or eliminated is up to you, but a professional can help decide the best options for you and the creatures.

Extermination of Fleas and Ticks
We love our pets, especially the furry kind like dogs and cats. They are members of our family and bring us a lot of joy. Unfortunately, they also may bring us ticks and fleas. Regular treatment of our pets can help prevent this problem, but once an infestation is in the home, it may be very difficult to eliminate the problem. Fleas can hide in the carpet and lay eggs and regular vacuuming may not be enough to get rid of them. Unfortunately, fleas and ticks live on the blood of animals, and human blood is just as good as dog or cat blood, but fleas and ticks can carry disease, such as Lyme Disease and plague.

Mice and Rodent Control
Mice in a home can be a problem as they breed and produce large litters in a relatively short period of time. In a year a female mouse may have up to 60 babies, which will be ready to begin reproducing within 10 weeks of birth (sometimes earlier). While mice may appear to be cute and cuddly creatures (to some), their droppings are unsanitary, and many mice carry the bacteria that causes salmonella. Additionally, mice can gnaw through walls, damage furniture, and make a mess in our homes. They also eat crops and food meant for livestock. As mice are a natural food source for many predators, too many mice in and around the home can cause there to be a large number of predatory animals, such as snakes, around our homes. As many snakes are poisonous, having a readily available food source for them can cause problems.

Mosquitoes hatch where there is standing water. If you live near a pond, lake, or swamp, you may have issues with mosquitoes and eliminating them may not be possible; however, there may be ways to prevent them from coming into your yard or home. Since mosquitoes can carry diseases, if you have a large number of them in and around your home, you may need to contact a professional to help you find ways to get rid of them.

Spraying for Spiders
It isn’t often that spider infestations in a home are an issue as spiders prefer to be where there is a food source; however, it is possible that your home offers such a readily available food source that you have an over population of spiders. While spiders can be beneficial, many of them are poisonous and can be hazardous to humans, such as the Black Widow Spider and the Brown Recluse. If you notice a large number of these in and around your home, you may want to consider eliminating them before someone gets bitten.

In addition to these common pests, there are a large number of insects that can affect crop production, including cutworms, snails, slugs, many types of beetles, and various rodents. Depending on how widespread the problem is, hiring a pest control company to deal with the problem may be the only solution to saving your crops.

Q: What is IPM?
A: IPM is Integrated Pest Management. The goal of IPM is to control pests by using the best control methods after carefully considering each method’s safety, effectiveness, cost, and its effect on non-target organisms and the environment. IPM does not necessarily eliminate the pest, but works to control it.

Q: Why should I hire a professional pest control company?
A: Sometimes the pest control problem involves the use of chemicals that may be harmful to humans and pets. It’s important to know how to apply the chemicals in a way that will protect you and everyone else in the home. A properly certified and licensed pest control company can provide someone who can do that safely.

Q: Shouldn’t all the baseboards in my home be sprayed?
A: No. It is not necessary and needlessly exposes people and pets to pesticide. Pests may live behind baseboards, or inside them, but never on them. If pesticides are applied, they should be applied to the cracks, crevices and voids where pests spend most of their time.

Q: If I want ongoing, periodic service, what should the service consist of?
A: Once any existing infestations are brought under control, any further service should involve ongoing inspection for further infestations, and treatment if further infestations are found.

Q: What frequency of service is best?
A: The frequency of service depends upon your situation and the type of pest involved. Once your pest problems are eliminated, you may choose to retain periodic service, but that service should focus on inspection and spot treatment of pests, if and where they are discovered, rather than routine pesticide application.

Q: Who can I call if I suspect my house is not being properly serviced?
A: First express your concerns to the technician who provided your service. If you’re not satisfied with the technician’s response, call the company. If issues still cannot be resolved, you can contact the Better Business Bureau, Attorney General’s office, or the agency that regulates structural pest control in your state.

Q: Are pesticides always necessary to control pests?
A: No. Not all pests require pesticide use. Many can be managed by using only less toxic formulations such as baits, dusts, and microencapsulate pesticides that present less risk of human exposure. Talk with your pest control service about which alternative pest control methods will be effective in controlling the pests in and around your home.

Q: Are pesticides safe? What if I am pregnant, or I have an infant or small children?
A: No chemical is absolutely safe. The U.S. Environmental Protection Agency (EPA) registers all pesticides, after determining that each presents tolerable risk when used according to label directions. Any use inconsistent with a pesticide’s label is a punishable violation of federal law. In general it is the misuse of pesticides that is hazardous, though the EPA recognizes that risks associated with pesticide exposure may be greater for pregnant women, children and infants, and takes this into account when registering pesticides. If you have any concerns about pesticide use, have your physician review the labels of pesticides that will be used in your home.

Q: How much should pest control service cost?
A: The best way to determine this is to compare estimates from several companies. It can be unwise to hire the company offering the lowest price, because there are many other factors to consider such as licensing/certification and reputation. The more information you gather, the easier it will be to decide if the price is right.

Q: Who do I call if someone is accidentally exposed to pesticides?
A: First call the Poison Control Center in your area. It’s best to have the name of the pesticide so you can inform the Poison Control Center, emergency medical technicians, and your physician. If you do not know the name of the pesticide, the technician or their company should be able to tell you, or you can check the service reports they gave you after each treatment. Always save these reports! They are required to show what pesticides were used. Follow the Poison Control Center’s instructions.
