Roof Rats - Baits

The Roof Rat is implicated in the transmission of a number of diseases to humans and to pets. They prefer to forage for food above ground in elevated areas indoors and out.

Nesting Materials

Catch those rats with Victor's® Roof Rat bait suggestions, such as nuts, berries and peanut butter. Tie the rat bait to a trigger to prevent that tricky rodent from stealing the bait without setting off the trap. For baits that cannot be tied (peanut butter, e.g.), use only small amounts of bait for best results.

Remember, some rats are harder to catch and are Neophobic or "extra cautious" of new objects that suddenly appear in their environment. For these cases, rat traps should be placed out, but left unset, and baited for a couple days prior to setting the traps. This will give the Roof Rat a chance to become accustomed to it.
