Are worms beneficial to the soil?

By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil.

What problems do earthworms cause?

The worms alter the physical and chemical properties of soils, changing the pH, nutrient and water cycles, and disrupting symbiotic relationships between soil fungi and roots (mycorrhizas). The earthworms also amplify the negative effects of droughts, warming climate, and deer grazing on native plants, Frelich said.

Can nightcrawlers carry diseases?

Nightcrawlers are edible, but they need to be cooked before eating them raw because of the risk that they might contain parasites or bacteria like salmonella.

Can nightcrawlers survive being cut?
