The Ohio Division of Wildlife has no general permit requirements for collecting spiders in Ohio. The Division requires that the collector obtain permission (preferably in writing) from the landowner before collecting. When collecting on public land this would involve contacting the public agency responsible for the area. This is particularly important if you may be collecting in ODNR natural areas, nature preserves, or Ohio State Parks. Some of these areas are closed to collecting and others will require a specific permit.
