Earwigs in House Plants
Since some earwigs prefer young plants, besides being a garden pest, the earwigs can become an indoor pest and feed on indoor plants.
Earwigs are commonly found under plant pots in the saucer that is used to catch water that drains through the soil. This wet and dark area is protected from sun. Outside, the earwigs might feed on decaying vegetation washed through the humus soil. Earwigs can attack the young plants, though, so watch for damage of plants, especially seedlings.
When plants are brought in, earwigs can remain in the saucers and prosper in the constant temperature of the indoor environment. They do need high moisture substrate, so even overwatered plant soil can be a host.
If it appears that earwigs were brought in with plants, remove the plant and shake out the earwigs outside. Dry the saucer and inspect the plant soil for other earwigs or eggs and remove these if found. Look around carpet edges inside to make sure that earwigs are not there. They can be vacuumed to remove; don’t forget to remove the bag.
