Consider hiring a licensed pest control professional for safe, effective control
If using poison, follow local laws and label directions exactly; place only in tamper-resistant bait stations
Keep children and pets away from all traps and bait stations
Clean up after removal using gloves and disinfectants; dispose of carcasses safely
Monitor activity for at least 2–4 weeks after the last sign before assuming success
Contact local animal control or a licensed exterminator if you have large numbers, ongoing damage, or cannot locate entry points
