What are occasional invaders?
Occasional invaders are those insects that spend most of their time living outdoors, but will occasionally find their way inside your home or business. Occasional invaders typically don’t cause any problems for people when living outside but they can become an annoyance once they've invaded your property. Some are even considered dangerous.
The most common species of occasional invaders living throughout our area of Ventura County are the following:
Centipedes
The centipede has an elongated, worm-like body with one pair of legs per body segment. Centipedes are yellow to dark brown in color and some species also have darker colored markings. Centipedes have large, claw-like appendages containing venom that they use to paralyze their prey.
Flies
Flies have a single pair of wings and compound eyes. One of the most common species of flies to invade homes throughout the Ventura and Santa Barbara area is the house fly. House flies are dark gray in color and have four black stripes on their thoraxes. They have specialized sponging mouthparts that they use to feed on liquids.
Ground beetles
Ground beetles make up one of the largest groups of beetles. They have hard, flattened bodies with vertical ridges on their wings; despite having wings, ground beetles are unable to fly. Their heads are the narrowest parts of their bodies. Most species are black but some are metallic blue or green, and may even have red or gold markings.
Millipedes
Millipedes are worm-like in appearance. They have cylindrical bodies that are dark brown or black in color and may have orange or red mottling. Millipedes curl into a tight ball when threatened. Depending on the size and species, they can have anywhere from 30 to well over 90 pairs of legs.
Powderpost beetles
Female powderpost beetles lay their eggs in the cracks of wood. The larvae tunnel through wood, leaving behind fine, powder-like dust. Adults are reddish-brown to black, in color and have elongated, flattened, and narrow bodies.
