need help identifying the spider

Asked July 21, 2014, 4:15 PM EDT

This spider has moved in and taken over at my house. I need help identifying it and getting rid of it naturally. The spider itself was highly aggressive to any web disturbance and has a highly extensive web network built up

This looks like one of the funnel weaver spiders. See and for details and suggestions for management of spiders in and around the home.

according to all images that I've seen of the funnel weavers the body and markings on the spider does not match it has a light and almost whitish hourglass shape on the belly as shown in the picture and a bulbous abdomen. it has also most notably ran off a burrowing wolf spider. and also the nest itself is suspended with no funnel. The image that was posted with the question includes the web that houses one of the spiders.

Here’s how I arrived at my opinion, keeping in mind that spider id from photos can be difficult and that spiders can be variable in appearance. There are five families of web-forming spiders that infest houses. (1) Cellar spiders. These resemble daddy longlegs, definitely not yours. (2) Orb weavers. These form the classic vertical, single plane spider web, so again, not yours. (3) Sheet web spiders. These are small slender spiders that rarely occur indoors. (4) Comb-footed spiders (widows and the house spider). Your web is similar to theirs, but the spider itself doesn’t look at all similar to members of this family. (5) Funnel-web weavers. The web could be that of a funnel weaver, if the funnel is hidden in a crevice or hard to see for any number of reasons. The spider itself fits the general body type of the funnel weavers. Regarding the bulbousness of the abdomen, females have much more bulbous abdomens than the males (see the male vs female photos in figures 5 and 6 of All of that said, the only way to be certain as to what you have is to have the specimen identified by an expert. That can be accomplished by following the submission instructions for the CSU Plant Diagnostic Clinic (
