What to look for

Winter lows around Fort Collins average near 17°F, so termites retreat deeper into the soil, though colonies under heated basements can stay active all winter. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.

Fort Collins sits in a semi-arid climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. For Fort Collins homes, the area is mostly urban, so termites pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by.

Mark sprinkler heads and any buried lines. Keep pets and kids inside while the crew works outside. Ask how long to stay off treated soil. Any drill holes in a slab or patio get patched. Soil treatments and bait stations need little prep. Clear a path along the outside walls. Move stored boxes away from garage walls.

What's your biggest concern about termite control costs?
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. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud.
What you can do yourself
Store-bought sprays usually kill only the termites you see. It also needs even coverage around the entire foundation. The product has to reach the whole colony. Treating an active colony is harder. Keep firewood away from the house. Fix leaks and clear gutters. Pull mulch back from the foundation. Some of the work is yours.
