Other species of earwigs have been observed to capture insects with their forceps and then devour them. If you capture different species and keep them alive indoors you too, can observe their habits and come up with some new observations on these seldom-studied insects. Control European earwigs are difficult to control. They can build up populations to the point where they are nuisance pests by their very presence. Although somewhat beneficial as scavengers, they can be pests in gardens and very bothersome in large numbers.
Spot spraying with a recommended pesticide can also be beneficial.
