Description

House-associated spiders; identification varies

House spider is a common name used for several spiders found around buildings. Some build webs in undisturbed corners, while others enter while hunting. They feed on other arthropods. Eggs are protected in silk sacs and spiderlings grow through molts; there is no larval or pupal stage.

Spiders develop from eggs to spiderlings and adults through repeated molts. They do not pass through insect larval or pupal stages.

What Attracts Them?

Insect prey
Quiet protected spaces
Clutter and undisturbed corners

How Do They Get Inside?

Gaps around doors or windows
Damaged screens
Stored items brought indoors

Signs of an Infestation

Webs in sheltered corners

Egg sacs near resting sites

Repeated spiders near prey

Activity in undisturbed storage

How Serious or Harmful Are They?

The name house spider does not establish risk. Most common house-associated spiders are not considered medically important, but uncertain specimens should be identified before handling.

Treatment / How to Get Rid of Them

What You Can Do

Vacuum accessible webs and egg sacs
Reduce clutter and insect prey
Repair screens and seal gaps
Avoid handling unidentified spiders

How Pest Guys Helps

The A-C-T Process: Assess. Communicate. Treat.

Assess — We inspect your property, identify pests and activity, locate nesting and hiding areas, and find contributing conditions.

Communicate — We explain our findings, discuss the recommended plan, answer your questions, and confirm understanding and agreement.

Treat — We put the agreed plan into action, perform the initial treatment, provide ongoing service, and monitor results to adjust as needed.

Frequently Asked Questions

What should I look for first?

Eight legs; many forms. Webs in sheltered corners. A clear photograph and the location of activity can help with identification.

What conditions should I check?

Start with insect prey. Vacuum accessible webs and egg sacs.

Does seeing one mean there is an infestation?

A single sighting does not establish the extent of a problem. Repeated activity, developing young, nests, or other evidence help us determine what is happening.

How does Pest Guys decide what to do?

We use A-C-T: Assess, Communicate, Treat. The pest, its location, and the conditions at your home guide the recommendation. We explain the plan and any preparation needed before service.
