House Spider Infestation

House spiders tend to leave a profusion of dusty webs in inhabited homes and are considered housekeeping nuisances.

The American house spider may have a body length of 5 to 8 mm. These arachnids have a round abdomen that is grayish to black with mottling.

House spider infestations often indicate excessive humidity levels inside a structure. In addition to controlling humidity levels, one may repair screens and weather strips around windows, doors, vents and other openings to reduce chances of spider infestations. Constant sweeping and vacuuming is also advised as a method of discouraging their proliferation.

Large numbers of indoor house spiders may indicate the presence of other pests which the spiders prey upon. It is best to contact your local pest control professionals for a consultation.
