Lafayette and Tippecanoe County experience stink bug fall invasions. September perimeter bifenthrin spray before aggregation on south-facing walls is the key prevention action.
🐭 Mice — Wabash River Agricultural Interface
Lafayette's Wabash River location and surrounding agricultural land creates significant fall mouse pressure. October exclusion work is the critical annual pest prevention action.
💡 Lafayette Pro Tip: Purdue University's large agricultural research campus creates unique pest awareness among Lafayette residents — the university's Cooperative Extension Service provides excellent local pest management resources.

🪪 Hiring a Licensed Pro in Lafayette
Pest control technicians in Indiana must be licensed through the
Indiana State Chemist Office. Before hiring, ask:
Can you provide your state license number?
What pesticides will you apply and what are the re-entry intervals?
Do you provide a written treatment plan and warranty?
Are you a member of the National Pest Management Association (NPMA)?
💡 Tip: Get at least two quotes. Prices in Lafayette vary significantly
by provider, and the cheapest quote isn't always the shortest path to resolution.

Most sprays kill foragers but miss the queen and colony. For lasting control, use slow-acting bait that workers carry back to the nest. Keep bait stations active for 2–4 weeks after activity drops — colonies typically have tens of thousands of workers.
How do I find a reputable pest control company in Lafayette?
Check for a current Indiana Office of the State Chemist license,
read Google and Yelp reviews from the last 12 months, and look for NPMA membership.
Get at least two in-person quotes — phone estimates are rarely accurate for serious infestations.
Is pest control safe for my kids and pets?
Most professional treatments are safe once dry (typically 1–4 hours).
Ask your technician for the specific products and their re-entry intervals.
For sensitive households, ask about low-toxicity options like baits, dusts, and IGRs
which minimize broadcast spray exposure.
What's the difference between one-time and ongoing pest control?
One-time treatments address an active infestation but provide no ongoing barrier.
Quarterly service contracts maintain a perimeter treatment that prevents re-infestation —
typically more cost-effective than repeated one-time calls once you've solved the initial problem.
