With the onset of cooler weather rats and mice start looking for a warmer place to spend the winter months. The migration to the inside will start in late September and continue through the winter months.
Entry points for rodents can be as small as a dime for a mouse and a quarter for a rat. Rodents are opportunistic and often enter through an open door.
The most common areas of entry are; the line leading into the home from the air conditioner, under the garage door, dryer vents with faulty flapper valves, and vines growing on the side of homes.
The best way to prevent rodent entry into your home is to walk around your home checking the areas listed above. If you can insert an object the size of a dime, seal it up.
