Residents in a Michigan town near Detroit have been hit with a huge influx of rats – so many that the town legislature is considering offering $5 for each dead rat brought in by citizens, reports local Fox affiliate WJBK. Residents are scrambling to find ways of preventing rats from entering their homes and contaminating their food and possessions, as well as effective means of pest control.
Keeping rats out
There are several ways to keep rats and other rodents from entering the home. In Detroit as well as many other parts of the country, the winter is frigid which affects both humans and rats alike. Rodents will seek out any warm shelter they can find, and they are skilled at finding entry points. Rats have nearly collapsible skeletons and can fit in any hole that is larger than their head (about the size of a quarter) so the best step is to plug any and all holes through which the pests could fit.
Feeling for air movement can also reveal an entryway for a rat, a report from Popular Mechanics details. It is important to go around the house and find any vulnerability to rats and other rodents. Also important are windows and doors – any crack in the framing should be sealed. All doors should close flush against the frame and be sealed tight. Vents for driers and air conditioners can also allow rodents into the home, but are easily blocked with screens.
Keeping them away
Rats and other small mammals are attracted to the bounty of free food that is provided by an uncovered garbage can or a backyard garden, so tying down all garbage can lids with weighted bungee cords can help keep rats from coming back. Gardens are best kept several feet away from the house in order to prevent rodents from dashing into an open door or window.
Piles of unattended boxes, lumber or other refuse will provide a shelter to rats that are trying to stay out of the cold. The rodents won’t have as easy an opportunity to settle when the yard is kept free of refuse.
Rat traps are inexpensive but vary in effectiveness depending on the environment. Professional pest control is required in many cases.
