Rodent, Rat and Mices
Rodents are warm-blooded mammals that, like humans, can be found throughout the world. They have oversized front teeth for gnawing and check teeth, which are adapted for chewing. Rodents chew on a variety of items available to them and cause great damage in and around homes.
Rodent tend to be rapid breeders. Some species breed year-round, and populations are maintained through constant reproduction. Because of the rodents’ body plan, they are capable of squeezing through spaces that appear to be much too small for them. All such holes should be sealed to prevent entry and reentry of rodents. A pest control professional should be contacted for assistance.
