I see rats running on my roof and want to trap them but I don’t think they will work up there. The shingles are slippery and it’s not flat. Can I use a one of our live traps effectively on my roof?
Live traps can be used most anywhere if the target animal is active and the trap is both secured and baited with something that will get the animal inside. The use of a live trap out in the open, where animals are foraging and running, can certainly work. The following image shows a good trap set on a slanted roof. In this situation, the targeted animals were leaving the attic from the corner so placement needed to be as close as possible to their exit hole.
The trap needed to be secured which can be done with nails or staples. The only warning here is that it’s best to use silicone caulking when using anything to anchor the trap. Apply the silicone to the nail or screw when it’s first installed. When the trap is removed, don’t take out the nail or screw but instead drive it all the way in. The silicone previously applied will insure the hole is water tight and this practice will keep the roof water tight.
