What You MUST Know About Spiders In Tennessee

“Honey, come kill this spider!”

How many times have you heard that? Or said that? Probably, like most Americans, a lot!

Spiders are everywhere and there are so many different species of Spiders that we feel like we see different kinds of Spiders all the time. And we probably do.

There are approximately 4,000 different Spider species in the Unites States and Canada. Over 40,000, yes, forty thousand, species worldwide. So, how do we know which are good Spiders and which are bad Spiders? Or, if you’re like my wife, they’re all bad and must die!

Let’s break it down a little bit. First, you should know that only a few of over 4,000 species in the United States can cause serious damage from a bite.

The Brown Recluse, or Fiddle Back Spider, (tell-tale sign of the Brown Recluse is the Fiddle shape marking on it’s back) venom can cause significant cutaneous injury with tissue loss and  necrosis.

The Black Widow (black shiny color, with a yellowish orange or red hourglass mark or dot on the underpart of the stomach) venom can be excruciating and deadly. One can experience a serious illness even with a little venom as it affects the nervous system. Other symptoms are nausea, abdominal pain, headache, fever, an extreme blood pressure increase and vomiting.

The Red Widow Spider (black abdomen with red spots border lined with yellow lines, with the rest of it parts in a reddish-orange color) venom is a neurotoxin that leads to muscle spasms. Only the female bite.

The Hobo Spider’s (adult has several chevron-shaped markings on their abdomen, has a brownish color and can reach a body length  of  1/3″- 2/3″ and the legs can reach up to 2/3″ to 2″) bite forms a blister within 24 hours which later breaks open and turns into an ulcer with liquid oozing out after a day or two. Frequently, a terrible headache is one of the complaints in addition to weakness, nausea, damaged eyesight, short-term loss of memory and fatigue.  Mostly found in the Northwestern United States.

The Wolf Spider (adult wolf spider can reach up to  1/2″ to an inch or more in length with a brown to grayish speckles, and a distinctive impression of a Union Jack on the upper stomach area) The bite can be very painful and is venomous but not fatal. Wolf Spiders are not aggressive but they will bite you if provoked.

The Tarantula (commonly come in black or brown in color with distinguishable body hair which they use as a defense mechanism against predators. On average measure 2 3/4” up to 12”) bites are excruciatingly painful and can last for a number of days, but no recorded deaths from Tarantula bites. Mostly found in the West and Southwestern United States.

So, that’s quite a list but at least it’s not 4,000 dangerous Spiders, right?!

Ok, so how do we keep these beasts from getting us? Well, in general there are 2 control methods for getting rid of Spiders.

1. Altering the environment in and around the home to make it less attractive to Spiders

2. Finding and destroying as many spiders as possible

Let’s look at altering the environment:

• Routine, thorough house cleaning is the best way to eliminate spiders and discourage their return. A vacuum cleaner or broom effectively removes spiders, webs, and egg sacs.

•Spiders prefer quiet, undisturbed areas such as closets, garages, basements, and attics. Reducing clutter in these areas makes them less attractive to spiders.

•Large numbers of spiders often congregate outdoors around the perimeter of structures. Migration indoors can be reduced by moving firewood, building materials, and debris away from the foundation. Shrubs, vines and tree limbs should be clipped back from the side of the building.

•Install tight-fitting window screens and door sweeps to exclude spiders and other insects. Inspect and clean behind outdoor window shutters.

•Consider installing yellow or sodium vapor light bulbs at outside entrances. These lights are less attractive than incandescent bulbs to night-flying insects which, in turn, attract spiders.

How about destroying them? Yeah, that sounds good! Yup, we understand. That’s where we come in.

By setting up a good barrier protection program around your home, we can dramatically reduce the presence of Spiders. To some degree, this treatment will destroy Spider populations, but it’s effective largely because we are able to control other insects with a perimeter treatment. If there’s no food for the Spiders to eat, they’ll just go elsewhere. Perfect!
