Any entomology experts out there?

Question

I am having a HUGE spider problem at my house. These suckers are EVERYWHERE. It is freaking me out because they look a bit like Brown Recluse spiders, but the ones I've gotten close to don't look like they've got the "fiddle" on their backs. They're fairly large, have long, narrowish bodies (abdomens?), and are extremely fast. I have never seen any spider move that fast. So what I want to know is, are there any spiders similar to the Brown Recluse, and what are they? Are they poisonous? I've seen what happens to Brown Recluse bites, and I don't want none of that. Any info would be great.

I normally would try to find the answer on my own before coming here, but I loathe spiders... I can't even stand to look at pictures of them, and I know any site I go to will have pics.

Thanks!

Ok.. maybe I should be a little more specific. They're not always exactly IN my house, they're AT my house, like in the yard, in bushes, in boxes kept in the yard... I've been seeing a lot of them ever since the shed in our garden was torn down a few weeks ago. We're doing major renovations in our yard, and I think the reason I'm seeing them everywhere is because we tore down their home; they find a new place, we "invade" the new place and force them out, they find a new place.. It's a vicious cycle. The only time I've seen them in the house is when I've left the back door open for a few hours at a time.

Answer 1

Brown recluse spiders typically don't wander freely during the day.

The only true identifier, as one poster mentioned, is their 3 pairs of eyes arranged in a a crescent shape (if you were looking at their top, or cephalothorax) and the fact they are a very plain, dull brown/tan. Unfortunately they share this characteristic with some other spiders as well.


They tend to find a spot in wood piles or or irregular areas that have "cubby holes" to hide in. They are not active hunters, like most spiders and wait for their prey to happen across their trap.

They are typically non-aggressive and will go through great trouble to avoid even moderately traveled areas. How even, if you stick your finger in their web and corner them, then *maybe* they'll bite you - or if you roll over on them.

Additionally, Brown recluse bites only create severe reactions in 20% of the population. The sluffing of skin and necrosis that has become legendary on the internet is an extremely adverse reaction. Most people who are bitten by brown recluses don't even know it, or assume it's just another spider or a large reaction to anything but a brown recluse.

Since recluses are generally nocturnal when moving and their initial bite is painless, it's hard to say *when* anybody has been bitten.

Be sure to keep your hose tidy in the mean time so they have no "comfortable" spots to set up shop. As for the backyard, chances are those spiders have always been there and you're noticing them now because you're concerned. I believe there was a statistic (lies and damned lies right?) that said there were hundreds of spiders per square yard of a natural environment. I'd say it's more like 50-100. If you go in the wild, and stare at a single spot of ground and let your peripheral vision kick in, you can literally see the ground move with bugs.

Since the "violin pattern" is not diagnostic, and other spiders may have similar marking (i.e. cellar spiders (Pholcidae family) and pirate spiders (Mimetidae family)), for purposes of identification it is far more important to examine the eyes. Differing from most spiders, which have eight eyes, recluse spiders have six eyes arranged in pairs (dyads) with one median pair and two lateral pairs. Only a few other spiders have 3 pairs of eyes arranged this way (e.g., scytodids), and recluses can be distinguished from these as recluse abdomens have no coloration pattern nor do their legs, which also lack spines.[1]

Recluse spiders build irregular webs that frequently include a shelter consisting of disorderly threads. These spiders frequently build their webs in woodpiles and sheds, closets, garages, and other places that are dry and generally undisturbed. They seem to favor cardboard when dwelling in human residences, possibly because it mimics the rotting tree bark which they naturally inhabit. The common source of human-recluse contact is during the cleaning of these spaces, when their isolated spaces suddenly are disturbed and the spider feels threatened. Unlike most web weavers, they leave these webs at night to hunt. Males will move around more when hunting while females don't usually stray far from their web.

Since you are seeing a LOT of them in your HOUSE, I'm pretty sure they aren't recluse spiders. Brown recluses are reclusive, you seldom see them. And there are quite a few spiders that somewhat resemble them.
Since you loathe these arthropodic invaders, get some boric acid powder or diatomaceous earth, and sprinkle a thin layer all over the place. These substances will kill animals without bones (e.g. insects and spiders) but won't hurt anything with bones, such as people, dogs, cats, birds, etc.

i'm no longer an entomologist, yet i'm examining biology in school, and that i'm taking entomology next semester, so i think of i are able to assist. To get into an Entomology type does not require which you be responsive to a lot of something approximately bugs. The pre-specifications for the path are Zoology and usual Biology. as quickly as you're taking those, you may sign up for entomology. one ingredient which you will learn in Entomology are diverse orders of insect. bugs are in phylum Arthropoda, subphylum Hexapoda, type Insecta, and that they make up many training. Butterflies and moths are so as Lepidoptera, bees and wasps are so as Hymenoptera, genuine flies are so as Diptera, and so on. understanding a number of this previous to time would help, alongside with the evolutionary courting between orders. In college you may wish to important in biology. once you complete college (in case you prefer a profession in entomology) you will maximum possibly ought to bypass to Graduate college. There you will artwork in you fascinated container. In college you ought to take numerous training no longer on the subject of your pastime, in graduate college, you do basically what you're attracted to.

Answer 5

Not sure what they are, but I've heard spiders don't like coconut oil. Get some coconut oil, and soak cotton balls in it, place in containers, and distribute around the house. Good Luck.

Answer 6

wandering spider=not as poisonous
