Pill bugs eat decaying vegetable material and are most active at night. They are known for their ability to roll into a ball.


Pill bugs live in moist locations. They are found under damp objects or under vegetable debris.


Pill bugs do not spread diseases or invade food products. However, the pill bug is often considered a pest when it gains entry into a home.


Pill bugs can be avoided by eliminating food sources such as vegetable or plant debris. If pill bugs enter a structure, they will often dry out and die.
