Spiders in Northeast Florida — Identification & Facts
A guide to the spiders you'll see around Northeast Florida homes — which pose little risk to people, which deserve caution, and what draws them indoors.
Spiders at a glance
Most spiders in Northeast Florida pose little risk to people and actually help control other insects. The two species that warrant caution are the black widow and the brown recluse, both of which can deliver a medically significant bite. Because spiders feed on insects, the presence of spiders often points to an available insect food source.
How to identify them
Black widow
Glossy black with a red hourglass marking on the underside of the abdomen; hides in undisturbed, sheltered spots like garages and woodpiles.
Brown recluse
Light to dark brown with a darker violin-shaped mark behind the head; reclusive, prefers undisturbed areas (less common but present).
Common house and yard spiders
Orb weavers, jumping spiders, and cellar spiders; not dangerous to people and beneficial, they're the majority of what you'll see.
Behavior & habits
Most spiders are solitary and build webs or hunt to catch insects. They settle where prey is plentiful — around lights that attract bugs, in corners, eaves, garages, and undisturbed storage areas. The vast majority avoid people and aren't aggressive.
Signs of an infestation
Webs in corners, eaves, and garages; egg sacs; and an uptick in spiders usually signals a healthy insect population for them to feed on.
Northeast Florida context
Our climate supports spiders year-round. Most are beneficial, but black widows do occur in sheltered outdoor spots like garages, sheds, and woodpiles, so it's worth using care when reaching into undisturbed areas.
When to call a professional
If you're seeing heavy webbing, recurring spiders, or any spider of medical concern, professional treatment addresses both the spiders and the insect population they feed on. Gray Pest Control removes webs and egg sacs and reduces the food source.
Common questions
Are most spiders in my house dangerous?
No — the large majority of spiders in Northeast Florida pose little risk to people and help control other insects. The black widow and brown recluse are the ones to be cautious of.
Why do I have so many spiders?
Spiders follow their food — a lot of spiders usually means a lot of insects for them to eat, so reducing the insect population helps.
How do I keep spiders out of the garage?
Reducing clutter, sealing gaps, managing lighting that attracts insects, and professional treatment of harborage areas all help.
