❓ Common Questions — Baltimore Pest Control

Why do ants keep coming back after I spray?
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 Baltimore?
Check for a current Maryland Department of Agriculture 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.
