Ant Control San Diego


Ant control around homes and businesses is our specialty. We pioneered an outdoor-only approach to eliminating ant infestations over 20 years ago, and have continuously perfected our least-toxic technique ever since.

Most other companies will insist on applying insecticides indoors to stop an ant invasion, and will usually spray baseboards and cabinets and even apply insecticide dusts into wall sockets. All of these are almost always unnecessary with our ant control approach. We use materials which take advantage of the ant’s natural behavior and biology to carry the control agents to the nest, where they infect and kill the colony.
Your R&D technician will carefully identify the ant species before they start and customize a strategy accordingly. In most cases, we will focus our efforts exclusively on the exterior, which is almost always where the ant nests will be. In the rare occasion of ants nesting in the structure, our techs may suggest a gel bait application to cracks and crevices not accessible to kids or pets. Even then, you won’t need to vacate your home or office or empty your cabinets.

Our landscapes create an ideal home for many common ant species, and ants will inevitably try to re-invade from the neighboring areas. Often it makes sense to keep the ants at bay with one of our preventive programs once we have gained control of the original invasion. It’s usually much easier and more convenient to keep them away than it is to start all over when the next invasion occurs!

Every R&D tech is trained to inspect and treat as much of your property as is necessary to achieve excellent control over your ant problem. We are not, for example, limited to any artificial 20-foot-from-the-structure policy. Your tech will also be hunting for wasp nests, black widows, and earwig (pincher bug) and cockroach harborage, and treating for these other pests as needed. Every service is completely guaranteed to your satisfaction!


Q: The ants are everywhere in my home, upstairs and down, and not just in the kitchen and bathroom. Don’t we need to spray inside to get rid of them?

A: Not with our approach. Some other approaches use spray treatments that drive ants indoors, and the ant invasion inside often worsens as a result, so they will spray the inside to try to minimize this effect. We get to the source of the problem – the ant nests. We stop the nests and all the other activity stops as well.

Q: I know the ants are living in the walls. I can see them coming in through light socket plates and following pipes into the house. Don’t we need to treat in the walls?

A: Ants entering through the walls is common, but it almost never means that’s where they live. Many ant species, especially Argentine ants, need a moist environment for their nest. They will frequently build the nest in a damp area in the landscape, enter the structure at the base of the wall outdoors, and follow plumbing or conduit to get inside. On rare occasions, one of the native ant species, like Odorous House ant, will nest in a wall void, or sometimes a plumbing leak will supply enough moisture for an ant nest. Your R&D technician is trained to find and expertly diagnose these situations quickly, but they will otherwise be able to find and eliminate the sources around the exterior.

Q: I have small children and pets – will they be okay?

A: Our ant control approach, like all of our services, is designed to solve a pest problem in a way that keeps potential exposure to a minimum. Most of the time, we can eliminate the need for pesticides inside your home, which greatly reduces the risk. We also spend more money on our materials so that we can stay on the cutting edge of the latest developments in selective, least-toxic control agents. In addition, we use a low-volume approach with custom designed backpack sprayers and pinpoint bait applicators. We are firm believers that less is more, and that outstanding insect control can be achieved at the same time.
