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
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
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.
