Read Washington County's pest list off its geography: hot humid summers and deep-freeze winters that push pests indoors in waves, and the result is a calendar dominated by carpenter ants, overwintering pests and house mice.
The county's vital statistics: 569 square miles (the 54th largest of 99 in Iowa), centred at 41.33° N, 91.73° W, and one of the 2 counties composing the Iowa City metro. Pest work here is done by metro-based providers under Iowa rules.
From Iowa City, Washington County lies about 12 miles to the south. Counties are not equal shares of a metro: at 569 square miles, Washington County accounts for around 48% 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 Washington County's blend of the two is its own.
