Inside, they check the garage, baseboards, plumbing gaps and the attic. They check the foundation, the soil line and nearby wood. The inspector walks the outside of the house first. Most inspections take an hour or two.
Termites or ants?

Ant antennae bend like an elbow. - Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
Drill holes in slabs or patios get patched afterward. Keep kids and pets inside while the Lake Havasu City crew applies the product, and ask how long to stay off treated soil. In Arizona, heterotermes aureus flies in late afternoon or early evening in July, August and September (UC IPM), the summer monsoon months; drywood swarmers fly in daytime in summer and fall. Flag sprinkler heads and buried lines. Move boxes away from garage walls. Clear a walking path along the exterior walls. Prep is light for liquid treatments and bait stations.
Mulch and termites.
Wood chips touching the siding trap the moisture termites are after. A dry gap along the house makes mud tubes easier to spot; in Lake Havasu City's dry climate the risk is irrigation and leaky hose bibs rather than rain. Pull mulch back from the foundation and keep the layer thin.

When to call for help
Call if you see mud tubes, pellets or an indoor swarm. Hollow-sounding wood is another clue. Buying or selling? Get a wood-destroying insect (WDI) report either way. Lenders often ask for one.
