Beneficial Because:
Ground beetles emerge from shelter beneath mulch or shallow burrows at night to hunt soft-bodied slugs, smaller beetles, or other small creatures that come within their range. Their shallow burrowing helps break down organic matter.
Food and Habitat:
Daytime shelter is critical for dark-colored ground beetles, which would quickly cook in hot midday sun. Ground beetles are active at night or during periods of rainy weather, so you may not see them often, despite their constant presence. Mulches, bunching grasses and established perennial plants can serve as conservation points for these important natural predators.
Attracting More:
Incorporate a few perennial vegetables (asparagus, rhubarb) or vigorous perennial flowers or herbs into your garden; they will provide year-round habitat for ground beetles. Composting sites also make fine habitat for these important beneficials.
