I know this is a weird question but I am looking for the most probably way to attract rats in my attic and have a camera with motion sensor pointing right onto it. I believe it's roof rats. Location: Bay Area.
So far, I placed a small board of plywood next to a rafter and put (a) peanut butter, (b) oatmeal and (c) two slices of salami on it. Nobody showed up.
Background: I do not want this to be a question about rodent proofing, hence my specific answer. But here's the story: Moved into a house two years ago and there was a rat problem in the past. While I have never seen or heard any indication myself, I found an old carcass in the attic and tons of droppings. I hired a rodent-proofing company with 5 years warranty which cleaned, sanitized and re-insulated the attic. I have since found droppings on the insulation battings and had the company come a few times. They re-adjusted the traps (none of which ever caught a rat) and two times they found and closed more entry points. On their last visit they spent hours diligently looking for the roof and are confident that all entry points are closed. But the uncertainty drives me crazy. I want to know that they are gone for sure, for my peace of mind, as well as having a proof for the company if not. I purchased two Wyzecams with motion sensor but did not catch a single instance. If there are any entry points left, I want to make sure I can bring them on the camera to bring back the company as quickly as possible. Hence I am looking for most likely approach to attract rats.
