Spiders in the Home: Identification and Inspection

A spider sighting does not automatically mean an infestation. Identification, repeated activity and the conditions around the sighting help determine whether service is needed.

What to look for

Record recurring sightings, egg sacs and newly appearing webs. Some spiders hunt without a capture web, while an old web may remain after its maker is gone. These clues help guide inspection but do not establish the species or size of a population.

Do not identify spiders from skin marks

Unexplained skin irritation is not proof of a spider problem. Seek medical advice for a concerning reaction. If you see a spider, photograph it from a safe distance; avoid handling an unidentified specimen.

Reduce shelter and entry opportunities

• Keep stored items organized and inspect items before moving them.
• Repair accessible screen and door gaps.
• Remove reachable webs where appropriate and watch for renewed activity.
• Report insect activity that may provide prey.

Plank can assess repeated sightings and discuss the identified spider, areas of concern and selected service. Tell us which rooms are affected and what you have already tried. Ask about preparation and follow-up rather than assuming every spider sighting needs the same treatment.
