What we publish
Identification data, geographic range, venom and clinical information, behavior, and pest-management guidance for the spider species most often encountered in U.S. homes. Each entry is built around extractable facts - measurements, ranges, LD₅₀ values, egg-sac counts, established U.S. range - that can be cited or quoted directly.
Who it's for
- Homeowners and renters trying to identify a spider they've found.
- Pest-management professionals needing a reference they can hand to clients.
- Public-health and clinical staff verifying bite presentations.
- Researchers and writers needing a curated, source-linked starting point.
- Writers and reference tools needing primary-source citations.
How we built it
Every species entry was written against university extension publications (UC IPM, UF IFAS, Penn State, Texas A&M AgriLife, Colorado State, Clemson, University of Kentucky), CDC NIOSH guidance, AMNH and Smithsonian taxonomy, and peer-reviewed journals including the Journal of Medical Entomology, Toxicon, and Physiological Entomology. The full source index lives at /data-sources.
What we don't do
- We don't sell pest-control services. No referral fees, no kickbacks.
- We don't sensationalize. Most spiders found in homes pose no medical risk; we say so clearly.
- We don't take undisclosed sponsorships. Any future commercial relationships will be disclosed inline.
