Ant control across San Diego County

Yes, it's the same job. Ant extermination, ants pest control, an exterminator for ants, ant exterminators near you, pest control for ants, and ant control all describe the same visit: identify the species, then bait the colony instead of killing the trail you can see. UC IPM is blunt about why: pesticide sprays only provide temporary control, and spraying ants indoors with pesticides will not prevent more ants from entering.

Because the ants you can see are a fraction of the colony, and the colony is outdoors. UC IPM says most ants live outdoors, that spraying ants indoors with pesticides will not prevent more ants from entering, and that pesticide sprays only provide temporary control and may not be safe to use indoors. It also warns against spraying pyrethroids outdoors on hard surfaces such as driveways or sidewalks or around the foundation of buildings, because those products pollute waterways. Baits work for the opposite reason: the ants take the product back to the nest where the entire colony, including queens, can be killed.

Size and damage. UC IPM puts carpenter ant workers at 1/4 to 1/2 inch, black or bicolored red and black, nesting in tree stumps, firewood, fence posts, hollow doors or window frames, and depositing sawdust-like frass outside the nest. Argentine ants it puts at 1/8 inch, dull brown. Carpenter ants don't eat wood as termites do, but they hollow it out to nest and may cause considerable damage, so the treatment target is the nest rather than the trail.

They clear the trail for a while and nothing more. UC IPM does tell you to vacuum trails, wipe them with soapy water, or spray with window cleaner, but it puts that alongside baiting rather than instead of it, noting that baits take time to work, so continue to clean up trails. None of it reaches the nest, and the colony keeps sending workers until the bait does its job.

Ask the company to show you every placement before it leaves, and read the label with the applicator. UC IPM says prepackaged or refillable bait stations or stakes are the safest and easiest to use, and that active ingredients in baits may include boric acid or borate, fipronil, avermectin, or hydramethylnon. Baits work by being carried back to the nest rather than by contact, which is why they sit in cracks, behind appliances, and along baseboards instead of on open surfaces. The product label sets the rules around food and pets, and a California licensee has to follow it.
