No matter how clean your house is, insects will eventually find a way inside. But you can minimize insect problems by hiring a pest-control specialist to inspect your home. Most specialists will want to talk to you before they inspect your home so that they'll have an idea of your most pressing concerns. The specialist will probably start looking for insects in the kitchen because the room's moisture and warmth often attract bugs. The specialist will also pay close attention to the basement, particularly if you have sliding glass doors.
Insects can come in through the openings around the jamb and in the track.
Keep your house clean inside and out. Dry foods such as cereal and cornmeal should stored in airtight containers. Firewood piles, shrub plantings and deck and porch areas should be kept as clean as possible. The specialist may set up monitoring stations to help identify the types of pests you're dealing with. The specialist can then identify the insect pest and devise a plan for controlling it.
