Many species of click beetles are seen as pests by farmers given their taste for corn, potatoes, wheat, barley, and onions.
Larvae are responsible for the damage, boring into the seeds and underground parts of plants. They can also attack lateral roots, slowing down the plant's growth. In some cases, the damage is enough to kill the plant.
Click beetles are not much of a nuisance in homes. A few might manage to sneak their way in from time to time but they pose no threat and there is no risk of infestation.
