Occasional Invader Identification

What are occasional invaders?

As their name describes, occasional invaders are those insects that invade our homes “occasionally” throughout the year. They spend most of their time outside but do move indoors when it benefits them. Some of the most common occasional invaders living throughout Maryland, Washington D.C., and Northern Virginia are silverfish, centipedes, millipedes, sowbugs, and clover mites.


Are occasional invaders dangerous?

Occasional invaders are usually not dangerous pests and don’t pose significant threats to people or property. These insects are annoying to deal with as they tend to invade in large numbers and are difficult to eliminate. Also, depending on the species, they do cause damage to personal items, contaminate food, and even deliver painful bites (centipedes). Occasional invaders, dangerous or not, should never be ignored when inside your home.

Why do I have a occasional invader problem?

The biggest reason why occasional invaders are in your home is that it is providing them with a suitable environment for them to live comfortably. Occasional invaders move into homes through cracks in the foundation and exterior walls when the weather outside becomes too harsh. Besides coming inside on their own, some occasional invaders (centipedes, millipedes, silverfish) come in on objects like newspapers, boxes, mail, potted plants, and outdoor furniture.

Where will I find occasional invaders?

Occasional invaders tend to live in similar outdoor environments. They prefer dark, damp areas, often near the foundations of buildings. Living close to our homes is what allows these pests to find their way inside so easily. Occasional invaders hide under mulch, landscape ties, compost piles, leaf piles, compost bins, and trash cans. Clover mites are lawn pests and live in grassy areas and clover. Inside they usually choose damp, dark areas like basements, bathrooms, crawlspaces, and laundry rooms to hide.
