Sowbug Control & Treatments

Sowbugs may leave their natural habitats at night, and crawl about over sidewalks, patios, and foundations. They often invade crawl spaces, damp basements, and first floors of houses and businesses at ground level. Common points of entry into buildings include door thresholds (especially at the base of sliding glass doors), expansion joints, and through the voids of concrete block walls. Frequent sightings of these pests indoors usually means that there are large numbers breeding on the outside, close to the foundation. Since sowbugs require moisture, they do not survive indoors for more than a few days unless there are very moist or damp conditions.

Sowbugs are scavengers and feed mainly on decaying organic matter. They occasionally feed on young plants, but the damage inflicted is seldom significant. If you do have young plants around your home, they could be there, making their way into your home or business by accident. Sowbugs thrive only in areas of high moisture and tend to remain hidden under objects during the day. Around buildings they are common under mulch, compost, boards, stones, flowerpots, and other items resting on damp ground. Another frequent hiding place is behind the grass edge adjoining sidewalks and foundations.

Sowbugs do not bite or spread disease. However, the sowbug is considered a nuisance pest indoors. Outdoors, they can cause damage to young plants. Mostly, you just don’t want them in your home or business and can give the perception that it’s less than clean. That’s a reputation killer whether it’s home for the holidays with family or guests coming into your business.

The most effective, long-term measure for reducing indoor entry of sowbugs is to minimize moisture and hiding places near the foundation. Leaves, grass clippings, heavy accumulations of mulch, boards, stones, boxes, and similar items laying on the ground beside the foundation should be removed, since these often attract and harbor sowbugs. Items that cannot be removed should be elevated off the ground.

Don’t allow water to accumulate near the foundation or in your crawl spaces. Water should be diverted away from the foundation wall with properly functioning gutters, down spouts, and splash blocks. Leaking faucets, water pipes, and air conditioning units should be repaired, and lawn sprinklers should be adjusted to minimize puddling near the foundation. Homes with poor drainage may need to have tiles or drains installed, or the ground sloped to so that surface water drains away from the building. Humidity in crawl spaces and basements should be reduced by providing adequate ventilation, sump pumps, polyethylene soil covers, etc.
