These insects are called occasional invaders. They live outside your home in bark mulches and ground covers.
When outdoor conditions are too wet, or too dry, or any number of other reasons that will cause them to migrate, they become your unwanted guests.
They are unsightly, wedged in the seam of your carpet and baseboards. Their presence a attracts spiders who feed on them and, in time you will have a complete eco-system operating in your living room.
Treatment:
Periodic exterior perimeter treatment with a micro-encapsulated residual is an effective way of keeping the population down. The chemical should be worked in and under the bark mulches.
We also recommend dusting in the weep holes of your brick veneer with a special water resistant dust that has a very small particulate, allowing for a good distribution in the wall voids.
