We're Growing!

Killroy ownership has never tried to be one of the largest local pest control firms, nor has it wanted to sell the company to a nationwide conglomerate. Our desire has always been to operate a family-oriented company; one where the customers and employees alike feel valued and have access to ownership without having to maneuver past layers of management. For over 61 years, Killroy has been a company that has embraced controlled growth. We have a philosophy of keeping not only our customers happy, but of retaining our employees as well. The average tenure companywide is 17 years.


Part of our growth strategy has led to some wonderful new additions to our team. We are pleased to introduce you to our newest technicians: Steven Sanchez, Eddie Ruiz, and Rudy Melendez. We are also welcoming back Dennis Hatfield. All of these individuals are fully licensed and bring years of experience with them.


Steven joins us as a structural pest technician as well as a termite inspector and treatment technician. Both Eddie and Rudy come to us as structural pest technicians. Dennis Hatfield worked for Killroy in both our Campbell and Tracy offices before he left to become a first responder, working for the Manteca Fire Department. With his fire-fighting schedule, he has some days free. He decided to "come back home" for those extra hours. We are very excited to welcome all four of these gentlemen to the Killroy family. If you see them in your neighborhood, please say hello. They might be your new personal, pest management professional.

Wet Winter = Mosquitos in the Spring

As the weather warms up following a very wet winter, mosquitos may be emerging. Local municipal or county agencies may authorize fogging in some neighborhoods. We can help when we come for your regular service by inspecting the yard, treating some of the foliage where adult mosquitos hide during the day, and alerting you to any standing water in your yard. But, we are a partnership, and this will require some diligence on your part. Mosquitos breed in standing water. Look for sources of it around your home or business, including flowerpot saucers, clogged gutters, unattended water features, abandoned swimming pools, even over watered areas of your lawns etc. Also, be sure to check with your neighbors for a cooperative effort. Mosquitos do not recognize property lines. Be sure to set a defensive, proactive border where you live.

Termite Talk

with Mike Ledesma

It's spring, and with all of the rain we've had this year, there could be potential problems under your home. Standing water, fungus damage, or subterranean termites could be lurking. After the sub area dries out you should schedule an inspection. We can possibly give you some tips on diverting the water with the use of sump pumps, French drains or other hydro methods.

As soon as the sun comes out you are bound to see subterranean termites swarming. This could be a good indication that there may be termite activity in your home or business. Even when the ‘swarming season” ends, it doesn't mean that out of sight, out of mind applies here. There can still be activity in or under your home. Let us help you put your mind at ease.

Killroy has been using Termidor® for more than 16 years, and it is still our go to method for successfully controlling subterranean termites. Termidor® is used at very low rates, and has virtually no odor, which means you and your family won’t notice a thing. Termidor works via a “transfer” effect. Once a termite comes in contact with it, they become a “carrier”. It does not die on contact, but instead transfers the material via preening with other termites, leading to complete eradication of the colony. This can be 2-6 times faster than a baiting system. There are a number of formulations available.

We often get inquiries regarding orange oil. The active ingredient is steam extracted delimonene. It is a “safe” product to use; it can even be found in fruitcake. We have looked into it and it will kill termites that come into contact with it. The inherent problem is getting it to every termite! Many of the termites, including the queens can be in inaccessible areas. How do you deliver the material to them? Orange oil is a contact kill. The termite that comes in contact with it dies there, or very close to where it was exposed. It cannot “transfer” it to the other termites as Termidor® does. It is not appropriate for subterranean termites.

Other termite treatments offered by Killroy Pest Control include fumigation and heat treatment. Give us a call.

Your best protection is a complete inspection.

We have many years of experience and will provide you with peace of mind regarding your greatest investment.
