Description, Elimination of Pillbugs, Roly-Polys
Pillbugs and sowbugs though similar are different bugs that fall into the pest category of occasional invaders. Sowbugs and pillbugs are crustaceans and are closely related to crayfish and shrimp, more so than to insects.
Often confused with sowbugs, one of the distinct differences of sowbugs and pillbugs is that a Pillbug has the ability to roll its body up into a ball resembling a small pill; a Sowbug does not roll into a ball. It is easy to see how the Pillbug became known as a rolly-polly.
Pillbugs prefer damp areas, which is why they are often found invading homes through openings close to patio doors, laundry rooms and basements. These bugs feed on decaying vegetation most often found in mulched areas around homes. The damp conditions and decaying organic debris are contributing factors for several occasional invaders such as millipedes. Elimination procedures for Pillbugs parallel those for millipedes and sowbugs.
If contributing conditions such as excess moisture can be controlled, it
would be a great aid in Pillbug elimination. In many cases found close to
flower beds, gardens, flower pots, landscaping, swimming pools, ponds or any
heavily mulched area, a good insecticide spray is to be used; granular insect
baits labeled for pillbugs and sowbugs are an alternative to sprays.
