Quick Answers

Are carpenter ants a problem?

Yes. Carpenter ants do not eat wood, but they tunnel through damp or soft wood to nest. Piles of fine sawdust near trim or a window are a sign.

Why do ants keep coming back after I spray?

Store sprays kill the ants you see, not the colony. Bait that workers carry back to the nest works better for most kinds.

Does an ant control company need a license in Montana?

Yes. Montana licenses or certifies anyone who applies pesticides on someone else’s property for pay, through its state pesticide regulator, most often the department of agriculture. Ask for the license number before work starts.

What to Know Before You Call About Ants

Odorous house ants, pavement ants, carpenter ants and Argentine ants are common in American homes. The fix depends on which ant it is.

Wipe up the trail with soapy water and keep food sealed. Do not spray a trail you want a pro to bait, since bait needs live ants to carry it home.

For carpenter ants, ask the company to look for the moisture problem that drew them in.
