Even though many species do hibernate during the cold season, not all do, making your home even more inviting. Insects like spiders, fleas, roaches, and bed bugs seem to ramp up their indoor activities during the fall and winter months. Rodents like mice and rats will chew through just about anything to seek shelter and warmth in your home.  Spiders just love to hang out in seldom used areas within your home, one, because it’s warmer, and two because it’s easier for them to find food as resources dry up.  Fleas will hitch a ride into your home with your pets, making your carpeted areas and furniture their breeding grounds. Roaches won't necessarily be affected by a nuclear blast, but they sure do attempt to make themselves at home in your warm kitchen to feast on your holiday fixings.  Another increasing winter pest problem is bed bugs, with visits from family or students home from college during the holidays. Be careful they aren’t bringing in these uninvited guests.  Even mice and rats find your warm home and easier access to food very inviting and may flock inside to make a cozy nest and feed.
