They are so smart..this year i may put a camera on the rat trap to see how they get the peanut butter off..sometime it triggers it but a lot of times it doesnt.
Cats are smarter than the rodents
Btw..i have a whole complicated set up to catch japenese beetles..and some animal comes in the middle of the night and eats them all...even sucks them out of the water pool beneath the trap..
And dont get me started on the battle with carpenter bees
I have no qualms about killing insects and pests
