Rodents can cause expensive damage. They love wire insulation.
You need to capture it one way or another before he spores serious expensive damage These guys are smart.
One morning I lost my internet, phone service, one hard wired camera, and garage door opener push button in my house . I found the fios fiber optic cable chewed through, a network cable to a camera cut clean through and low voltage wire to my garage door opener button cut clean in my attic.
After getting it all fixed I put a camera in my attic, placed some bait up there and set it for motion detection. This is what I captured.
I first tried small live animal trap but he/she just ate the peanut butter and left.
I then set up several old fashioned rat traps and got him 2 days later.
