Climate & local factors NOAA Climate Normals
- Cold winters slow outdoor pests, but rodents move indoors seeking warmth — late fall and winter are prime mouse-and-rat season here.
- A recurring quarterly plan is usually cheaper per visit than repeated one-time calls — and keeps problems from rebuilding between visits.
- DIY prevention — sealing entry points, fixing moisture, and storing food well — meaningfully cuts how much treatment you need.
- Bed bugs and wildlife removal are specialty jobs priced separately from general pest control; get a specific quote for those.
