Traps vs. Baits: What works best for you? Traps or baits can be used stand alone or together as part of a system of rodent control to make sure you cover all bases. Go outside and see if you can find any holes in the ground that weren’t there before. The method you choose to control your rat problem depends on your preferences. Can you stand seeing the rat once it’s caught? The major difference is that a trap physically holds the rodent in place. This is ideal if you want proof that the rodent was caught or for tracking purposes. Trap types include glue traps, mechanical traps, or even catch-and-release traps.
