The term “potato bug” can refer to two different pests: the Colorado potato beetle (a garden pest) and the Jerusalem cricket (a large, nocturnal insect). In Southeast Alaska, most references to “potato bugs” typically mean the Colorado potato beetle, which is a destructive pest to gardens and crops, especially potatoes and other nightshades.

Pill bugs seek out moist environments to survive. They often enter homes through foundation cracks, under door thresholds, or around plumbing areas. Outdoors, they’re found under mulch, stones, or rotting wood. Excess moisture is the main attractant.

No, pill bugs are not harmful to people or pets. They don’t bite, sting, or carry disease. However, they can be unsightly indoors and may occasionally nibble on soft plant seedlings in gardens or greenhouses.

To prevent pill bug invasions:

• Reduce moisture: Use dehumidifiers and fix leaks in basements or crawlspaces.
• Seal entry points: Caulk cracks and gaps in foundations and around windows and doors.
• Clear debris: Keep mulch, leaves, and wood piles away from the foundation.
• Improve drainage: Ensure gutters and downspouts direct water away from your home.

Pill bugs primarily feed on decaying organic material like dead leaves, mulch, and compost. In very damp gardens, they may feed on soft roots, seedlings, or fruit that touches the soil.

Pill bugs can live up to 2–5 years under favorable conditions. They reproduce slowly compared to insects, but colonies can grow over time if moisture and shelter are available.
