Spider Control in Sitka, Alaska

Spider control in Sitka is usually about the giant house spider, the barn funnel weaver, and the daddy longlegs. These are the species that make it into the homes, the cabins, and the crawl spaces around town, and they are almost entirely harmless. The giant house spider is the one that gets the most attention because it is fast and large, but it is a nuisance pest, not a medical threat.

The reason spiders are common in Sitka homes is the same reason a lot of pests are common: the damp, the wood-frame construction, and the forest edge. Spiders eat insects, and the insects are plentiful in the crawl spaces, the attics, and the wall voids. A spider problem is almost always a sign that there is an insect problem the spiders are feeding on.

Common spiders in Sitka

• Giant house spider — the most common indoor spider. Large, fast, brown with a patterned abdomen. Builds a funnel-shaped web in corners, basements, and crawl spaces. Harmless.
• Barn funnel weaver — similar to the giant house spider but slightly smaller. Found in basements, sheds, and garages. Harmless.
• Daddy longlegs — the long-legged spider that gathers in the corners of the ceiling. Builds a loose, messy web. Harmless.
• Cross orbweaver — the garden spider that builds the classic circular web in the bushes and the eaves. Found outdoors, not indoors. Harmless.
• Black widow — extremely rare in Sitka. The last confirmed sighting in Southeast Alaska was in a shipment of grapes. If you find a black, shiny spider with a red hourglass on the underside, call us.

Why spiders are in your Sitka home

• Food supply. If there are flies, mosquitoes, ants, or other insects in the house, the spiders will follow. The spider population is a measure of the insect population.
• The damp crawl space. The damp, dark crawl space under a Sitka home is a perfect spider habitat. It is cool, moist, and full of the insects spiders eat.
• The fall migration. Spiders are more visible indoors in the fall and early winter, when the cooling temperatures push them inside.
• Outdoor lighting. The lights on the porch, the garage, and the deck attract insects at night, and the spiders build their webs in the light to catch them.

How spider control works in Sitka

1. Inspect. The technician identifies the species, the harborage areas, and the food sources. The crawl space, the attic, the basement, and the exterior eaves are the priority.
2. Treatment. A residual insecticide is applied to the baseboards, the corners, the window frames, and the crawl space. The exterior treatment covers the eaves, the porch lights, and the foundation.
3. Web removal. The webs are knocked down with a brush or a vacuum. Removing the webs removes the spiders and the egg sacs.
4. Prevention. The entry points are sealed, the outdoor lighting is reduced, and the homeowner is advised on the sanitation and moisture steps that reduce the insect population the spiders feed on.

Preventing spiders in Sitka

• Reduce outdoor lighting. The insects that spiders eat are attracted to the lights. Yellow bug lights help, but turning the lights off is better.
• Seal the gaps around doors, windows, and utility lines. Spiders are small enough to fit through any gap that lets insects in.
• Keep the crawl space dry and clear of clutter. A dry crawl space has fewer insects, and fewer insects means fewer spiders.
• Vacuum the webs and the egg sacs regularly. A vacuum is the most effective spider control tool for light infestations.
• Trim the bushes and the branches away from the house. The spiders build their webs in the vegetation, and the branches give them a bridge to the structure.

If you are tired of walking through webs in the doorway or finding spiders in the bathtub, start with a free inspection. A local Sitka technician will identify the species, treat the harborage areas, and build a plan that keeps the spiders out without the heavy chemicals.
