Start from the county. In Arizona, 7 counties fall inside the metros PestReach USA covers — the Phoenix, Tucson, Prescott, Lake Havasu City, Yuma, Flagstaff areas among them — adding up to about 69,343 square miles. Pest pressure is read at this level because it is the level providers work at: routes, licensing and local rules all resolve to county and metro long before they resolve to state.
Read down the list and the pattern is geographic: the counties nearest a metro core carry its density problems, the outer counties carry the edge-of-development ones — new subdivisions against farmland and woodland — and every county page on this index sets out which pattern applies there, and why.
By land, the covered counties run from Coconino County (18,616 sq mi), Mohave County (13,332 sq mi), Maricopa County (9,202 sq mi) down to Pinal County at about 5,367 square miles. The metros anchoring coverage are Phoenix (metro population 5,228,938; 2 covered counties in Arizona); Tucson (metro population 1,074,685; 1 covered county in Arizona); Prescott (metro population 252,552; 1 covered county in Arizona); Lake Havasu City (metro population 228,102; 1 covered county in Arizona); Yuma (metro population 224,449; 1 covered county in Arizona); Flagstaff (metro population 144,368; 1 covered county in Arizona). Those numbers are the frame for everything on the county pages below: area sets how rural a county reads, the metro sets its pest calendar, and the two together set what providers actually deal with there.
The state's pest calendar is anchored by its largest metro, Phoenix: about 7 inches of precipitation a year, an average temperature near 76°F, roughly 173 days at 90°F or above and 1 days at or below freezing. Every county in this index lives inside that weather pattern, adjusted by its own distance from the metro core.
Statewide, the recurring names on county pages are bark scorpions, drywood termites, roof rats, black widow spiders, house mice — the signature of desert, mountain desert country. The biggest covered county, Coconino County (18,616 square miles), is served through the Flagstaff metro; metro-level guides live on the Arizona state page.
The communities county residents actually name: Phoenix (about 1,624,832 residents), Tucson (about 543,348 residents), Mesa (about 507,478 residents), Chandler (about 278,123 residents), Gilbert (about 271,118 residents), Glendale (about 250,193 residents) are the largest covered communities on this index; each sits inside one of the counties above, and its county page carries the local pest reading for that ground.
