Living organisms need food, water, and harborage (a home) to survive. If you have pests in your home, the pest has found a reason to be there. Either the pests are gaining access from the outside, or they are being brought in from an external source. Take a look at places where pests may gain access. Can you see daylight around door and windows? If so, install door sweeps or weather stripping to seal those access points. Take a look at plumbing vents. If pests are gaining access there, install screening over the vent. Another location pests may enter a structure is around the plumbing. Escutcheon plates should be sealed to the wall. Plumbing pipes are often used as roadways by pests. Closing the access point into the home will exclude the pest. If pests are entering when doors are opened in the evening, consider changing the angle or type of outdoor lighting. Once access points have been sealed, you still must remain vigilant that pests aren't carried into the home on items. Cardboard is often a culprit when it comes to pests. Be sure to check boxes and bags for fecal smears, egg cases, or other evidence of pests.
