Larimer County does not have a separate pest problem from the Fort Collins–Loveland metro — it has the local edition of it, printed across 2,596 square miles of Colorado.
In Larimer County the pattern is set overhead and underfoot: arid heat, cold nights and pests that shelter in the same walls people do above, and housing that gives those pests their harbourage below. black widow spiders and house mice are where the two meet most often.
Larimer County covers 2,596 square miles of land — the 9th largest of 64 counties in Colorado by land area, on US Census figures — centred near 40.66° N, 105.49° W. It is one of 1 counties that make up the Fort Collins–Loveland metro area, and pest services here are delivered by providers based in that metro, working to Colorado licensing rules.
From Fort Collins, Larimer County lies about 0 miles to the east. Counties are not equal shares of a metro: at 2,596 square miles, Larimer County accounts for around 100% of the total county land in this one, and it is a mid-sized county for this metro. Pest pressure tracks those proportions loosely but honestly — more open land means more wildlife and field-pest interface; tighter settlement means more of the pests of density — and Larimer County's blend of the two is its own.
