Spider Control in Asheville, NC

The spiders Asheville homes see

Common house spiders build funnel webs in corners, behind furniture and in the garage. They are the spiders most people picture when they say spider: brownish, quick, and gone the moment the light comes on. Cellar spiders — the long-legged ones — hang upside down in messy webs in basements, crawl spaces and the corners of low rooms, and they stay put for months. Wolf spiders do not build webs at all; they hunt on the ground, and they come indoors in autumn when the weather turns, usually through the garage or a ground-floor door. Jumping spiders are the small, quick ones on the windowsills and walls in summer, hunting flies in the daylight.

Two species get asked about most and seen least: the black widow, which favours undisturbed places like woodpiles, sheds and crawl spaces, and the brown recluse, which is uncommon in the mountains but is reported often enough that providers check for it in storage areas. Identification matters here — the treatment for a house spider is not the treatment for a widow in a woodpile, and the provider identifies the species before deciding the approach.

What the inspection covers

The inspection walks the rooms where webs keep appearing, the garage and the crawl space, and the outside of the house — the eaves, the window frames, the vents and the foundation line. The provider identifies the species from the web shape, the egg sacs and any spiders found, and looks for the two things that decide the plan: where they are entering, and what they are eating. A house with a fly problem at the windows will keep drawing spiders no matter how many webs are cleared, so the insect pressure gets checked at the same time.

How spider control works

The work has three parts. First, the webs and egg sacs are removed — webbing brushed from corners, eaves and vents, and the sacs collected so they do not hatch later. Second, the entries are dealt with: gaps around windows and doors, torn screens, vents without covers, gaps where utility lines enter. Third, the insect pressure is reduced, because fewer insects at the windows means fewer spiders hunting there. A residual treatment may be applied to the corners, eaves and entry points where the plan calls for it, and the provider sets out the schedule and what to watch for between visits.

Spider work is seasonal. Spring and summer bring the web-builders to the eaves and the corners; autumn brings the hunters indoors through the garage and the ground-floor doors. A visit timed to the season — before the autumn move indoors, for example — does more than a visit after the webs are already everywhere.

The problem and the solution

Keeping spiders out

Clear the webs regularly — a web that is left alone becomes a nursery. Keep storage off the floor in the garage and the crawl space, and shake out boxes that have sat undisturbed. Seal the gaps at windows and doors and repair torn screens, because spiders enter through gaps most homeowners would swear were sealed. Keep the outside lights in mind: lights draw insects, insects draw spiders, so the webs cluster around the brightest fixtures. And keep the woodpile away from the house wall — it is the one place a black widow is most likely to be found.
