[ 01 ] The short answer
Which pest leads in your state
The most-searched household pest per state, from Google search interest across 30 common pests. Source: Organic Lesson, “The Most Troublesome Household Pests in Each State,” Google Trends analysis of 30 common household pests, reported by Pest Control Technology.
This is search interest, not an infestation count. It tells you what people are asking about, which is not quite the same as what is in your house — but it is a reliable signal of what your neighbours will be dealing with.

[ 03 ] All guides
Every state guide
Grouped by climate region, because that is what actually predicts the pest list.
Midwest
Hot summers, real winters, and moisture as the recurring underlying cause.
Northeast
Hard winters that genuinely stop insect activity, humid summers that restart it.
Mid-Atlantic
A long active season and older housing stock with plenty of shared entry points.
Southeast
Long hot humid seasons, heavy rainfall, and near-continuous pest pressure.
Mountain & West
Dry, high-altitude conditions where elevation changes the pest list over short distances.
Pacific & West
Wet mild winters and dry summers, with a sharp wet/dry split.
South Central
Long seasons warm enough for continuous activity, with high structural pest pressure.
Gulf Coast
Year-round warmth with no freeze to reset insect populations.
Next step
Start with the pest, not the state
Regional timing changes when a pest arrives, but it does not change how you get rid of it. Identify the species first, then follow the plan for that pest — and use the state guide for when to start looking.
