Who This Is For

Written for renters, facility managers and anyone else in St. Clair Shores who's dealing with ants or wants to keep them out.

The Problem

Leave it and the colony grows. A carpenter ant satellite nest indoors may hold workers, pupae and larvae but usually no queen, which stays outdoors. Ants are drawn to St. Clair Shores homes by the same things every season: water under a sink, pet food left out, honeydew from aphids on the shrubs by the wall. Remove the draw and the traffic drops.

Warning Signs

•Ants trailing up exterior walls to the roofline.
•Shed wings on sills or in spiderwebs.
•Large black ants active indoors after dark.
•Faint rustling inside walls or hollow-sounding trim.
•Steady lines of ants along baseboards or counter edges.
•Trails appearing after heavy rain.

Risks of Waiting

⚠Structural repairs when carpenter ants go unnoticed for years.
⚠Stored pet food and pantry goods ruined.
⚠Rising costs as a small trail becomes multiple nests.
⚠Failed rental or restaurant inspections.
