Chelicerae (fangs) fused at base, cheliceral claw short and opposed (closes to/opposite) by a short toothlike projection of basal segment. Usually with 8 eyes, some species with 6, usually with 2 widely spaced groups of 3 closely-spaced eyes each and 2 eyes in between. Color usually pale yellowish to light brown or gray. RECOGNITIONĪdult body length ranges from about 1/16-5/16" (2-8 mm) cephalothorax and abdomen connected by tiny waist (pedicel) but appearing as small body with very long, thin legs. About 20 species are found in the United States and Canada. Cellar spiders are nuisance pests, probably more because of their webs than the spider itself. The common name cellar comes from these spiders being frequently found in dark and damp places such as cellars, basements, and crawl spaces, and that of daddylonglegs from their very long, thin legs which give them an appearance somewhat similar to harvestmen/daddylonglegs (order Opiliones, family Phalangiidae see similar groups below). Longbodied cellar spider.The Daddylonglegs Spider Common Name: Cellar or Daddylonglegs Spiders Scientific Name: Various Class/Order/Family: Arachnida/Araneae/Phoicidae Metamorphosis: Simple INTRODUCTION Repeat this every few weeks until no new webs are seen. Systematically move through your house, removing all webs and spiders. Insecticides are not very effective at controlling these spiders for a few reasons 1) the spiders don't move around that much so the chances of them walking through a residual insecticide are not good 2) even if they do walk through the insecticide they are walking on the tips of legs on claw-like tarsi, and 3) insecticides are often not as effective as we want because spiders are not insects, they are arachnids.įor cellar spider control the best thing is a vacuum with a hose attachment. Often the spiders and webs are concentrated in a dark, seldom disturbed, basement or cellar area. Long-bodied cellar spiders are difficult to eliminate from a home. Long-bodied cellar spiders are not poisonous to humans and are actually sort of good guys because they eat insect pests, house centipedes, and other things we do not like in our homes. Long-bodied cellar spiders leave what seem to me to be permanent webs in basements, corners of ceilings, walls, book shelves, basically just about anywhere. Sometimes long-bodied cellar spiders are seen hanging in their web, but most often just the webs are seen because the cobwebs do not become obvious until they are old and abandoned by the spider and have gotten covered in dust. Long-bodied cellar spiders have a long body that is usually a bit less than 1/3 of an inch, and very long thin legs that can make the spider seem quite large. In Iowa the most common species of spider that makes cobweb-like webs is the long-bodied cellar spider. There is a group of spiders we call the cobweb spiders, but many species of spiders make messy webs we would call cobwebs. Cobweb is a term used for messy spider webs in homes, the flimsy webs that sort of drape down and get covered in dust.
