Frequently Asked Questions

Do I need to leave the house during ant treatment?
Foam or dust in a wall void is contained. Your Las Cruces technician will say if anything different applies. Usually not. Ant work in Las Cruces is mostly gel baiting and a low perimeter band, and most pros ask only that you keep kids and pets away from treated spots until they dry.
Will ant control also handle fire ants?
Pros in Las Cruces typically use a broadcast granular bait across the lawn followed by individual mound treatment. Ask specifically for fire ant service when booking in Las Cruces, since not every ant plan includes the yard. Yes where they occur, but the method differs.
Why are ants in my bathroom when there is no food?
Trails under the vanity usually point to a leak. Fixing the drip matters as much as any bait a Las Cruces technician places, so mention it when you book. Bathrooms in Las Cruces homes supply the one thing ants cannot skip: water.
What is the difference between carpenter ants and termites?
Termite damage is mud-lined and hidden. Either way, a Las Cruces inspection settles it and the treatments are completely different. Frass is the giveaway. Carpenter ants in Las Cruces push clean, fine debris out of their galleries, often with insect parts mixed in, and the wood inside is smooth.
What should be included in an ant treatment visit?
For carpenter ants in Las Cruces, add nest location and direct void treatment. If a Las Cruces quote is just spraying baseboards, keep looking, because that approach rarely reaches the colony. At minimum: identification, matched bait, entry-point treatment and a follow-up date.
Do ants infest office buildings?
For Las Cruces homes, yes, ants move between units and floors along shared walls, plumbing, and wiring. For Las Cruces homes, in apartments and offices, controlling them usually means finding the shared trail and treating at the source, and coordinating with neighboring units so the colony is not just pushed back and forth.
Do people actually move because of a pest infestation?
For Las Cruces homes, rarely on their own, but carpenter ants can damage wood badly enough that repairs are needed, and a persistent ant problem can be a real nuisance. For Las Cruces homes, most ant issues are resolved by locating the nest and baiting or treating it directly.
