Texas has the privilege of dealing with both Rats and mice. We see a lot of the House Mouse, Roof Rat, and Norway Rat. Rats and mice can squeeze in through a space as small as 1/4". Make sure you seal all entry points to your home and eliminate food/water resources. Anything already living in the house will be trapped. We do not put bait in a house to keep the mice or rats from expiring inside. Snap traps are most preferred for inside work.
