When it comes to pest control, the old saying an ounce of prevention is worth a pound of cure could not be more accurate. I have a few suggestions that might help you avoid pest problems in the future. Keep bird feeders at least 25 feet from the house, rodents will be attracted to the seed that falls to the ground when birds feed. If you store pet food outside make sure it is in a container that cannot be chewed through, one that closes tightly. In warm weather do not allow water to collect in the gutters, toys that stay in the yard, or any other item that might hold water, this will help to prevent mosquito breeding. Do not stack wood against the house, this practice will create a home for all kinds of pests, among them rodents, snakes, and ants including carpenter ants (wood destroying).
