Norway Rats - Baits

They spread diseases as they eat and contaminate food. They damage property by gnawing and burrowing. A half-inch opening is all they require to gain access to your home. They can eat nearly any type of food but prefer meat and fresh grain.

Tying the rat bait to the trigger will prevent the rodent from licking or nibbling the bait and stealing it without setting off the trap. For rat baits that cannot be tied (e.g. peanut butter), it's best to use small amounts.

Remember, some rats are harder to catch and are neophobic or "extra cautious" of new objects that suddenly appear in their environment. Some rats can be extra cautious so leave an unset rat trap out for a few days before setting it with rat trap bait. This will give the rat a chance to become accustomed to it and to be caught by it.
