Spider Control in Hampton Roads
Most spiders in a Virginia home are harmless and even useful. The black widows living in your crawl space are the reason we still take the category seriously.

Web position and gloss. A messy low web in a garage corner is a different finding from a web at the porch light.

Description
Wolf spiders, cellar spiders, and orb weavers make up most of what homeowners see, and they are pest control in their own right, eating the insects that actually cause problems. The species that changes the conversation is the southern black widow, glossy black with the red hourglass, which favors exactly the environments our technicians work in daily: crawl spaces, meter boxes, wood piles, and cluttered garage corners. Finding widows during crawl space work in Hampton Roads is routine, which is one more reason homeowners should not be crawling under their own houses.
A heavy general spider population is usually a symptom, not the disease. Spiders go where prey insects are, so a house wearing webs on every corner is telling you about its insect population and its exterior lighting.
Field indicators
Evidence, in the order it is usually found
With spiders the web tells you more than the spider does, because where the web is built is the identifying character.
- 01 Messy, low webs near ground level in garages and crawl spaces, the widow signature
- 02 Glossy black spiders with a red hourglass under shelves or in meter boxes
- 03 Web buildup at soffits, shutters, and porch lights
- 04 Egg sacs tucked into corners of storage areas

Grade level
Where it lives in the structure

Roof and attic

Living space
Cluttered garage corners and storage areas, where egg sacs get tucked into the corners.
Exterior wall, trim, and deck
Web buildup at soffits, shutters, and porch lights, which is a reading on exterior lighting more than on spiders.

Consequence
What it costs to ignore
The honest answer is that most of it costs nothing, and one part of it does not.
Most spiders
Wolf spiders, cellar spiders, and orb weavers are pest control in their own right, eating the insects that actually cause problems.
Widows
The southern black widow favors crawl spaces, meter boxes, wood piles, and cluttered garage corners, which is one more reason homeowners should not be crawling under their own houses.
What it signals
A house wearing webs on every corner is telling you about its insect population and its exterior lighting.
Corrected condition
A void that is no longer a void
Widow habitat is dark, protected, and undisturbed. Sealing and lighting the crawl space removes all three conditions at once.

Correction
What we do about it
Remove, treat the harborage, and take away the prey population that sustains the whole thing.
We remove webs and egg sacs, treat harborage zones like crawl spaces and garage perimeters, and knock down the prey insect population that sustains heavy spider activity. For widow-prone properties we pay specific attention to the dark protected voids where they establish, and we flag them whenever we find them during any inspection.

Spiders: quick answers
01 Are brown recluses a problem in Hampton Roads?
True brown recluses are rare in coastal Virginia, and most suspects turn out to be harmless look-alikes. Black widows are the venomous spider we actually find here, and they favor crawl spaces and outdoor voids far more than living areas.
