Cold weather does kill many types of bugs. This is why they seek out warmth with such strong determination and why they will try to get into your home if possible. \
Some bugs can survive freezing temperatures if they go deep enough underground or create warm nests to shelter in while waiting out the winter. This means that problem bugs around your property might not really go away and end up resurging when the weather gets a little warmer. \
It's a good idea to regularly spray around your home once a year to prevent and kill bugs. This will help provide constant prevention and cause existing bugs to die. \
