Occasional Invader Identification & Prevention

What are occasional invaders?

Earwigs and silverfish are examples of occasional invaders that regularly make their way into our Texas home. They often call the damp soil near our houses home. During periods of dry weather, heavy rains, or other unsuitable weather conditions, they will move indoors. Occasional invaders seem to pop up unexpectedly; one day, your home is pest-free the next day, home to uninvited pests!

A brief description of the earwig and silverfish are listed below:

• Earwigs have a long, slender body, flattened from top to bottom that is dark brown to reddish-brown. Earwigs have forcep-like appendages (cerci) that extend from the end of their abdomen- their most identifying feature. 
• Silverfish have antennae as long as their body, and their brown, carrot-shaped body is covered in silvery, metallic scales; a three-pronged appendage extends from the hind end. Silverfish scurry from place to place using a distinct wriggling, fish-like motion.

Are occasional invaders dangerous?

Most occasional invaders, including earwigs and silverfish, pose no significant danger to people nor our property. They are nuisance pests that are simply using our homes as a place of shelter. However, just because they aren’t a danger doesn’t mean we should ignore their presence. Having occasional invaders in your home usually indicates that areas of your home are damp, as most of these insects have high moisture needs. Also, if occasional invaders are finding a way into your home, so will other pests that are likely to be more problematic.

Why do I have an occasional invader problem?

Earwigs and silverfish live outside in damp, dark areas. Often the mulch in flower beds and gardens surrounding our homes are where these pests live. Other places that occasional invaders gather near our homes include the ground under woodpiles, trashcans, and flowerpots.

The occasional invader’s proximity to our homes allows them to easily migrate inside whenever they see fit. People can also introduce these pests into their homes on or in things like pieces of firewood, storage boxes, plant pots, and other items that have been outside and are brought back inside.
