As for the Brown Recluse, I have done all the homework and with no time to spare, from what I learned on line will make it sound like I'm making this up, but listen closely. It's a story about control in today's world of medicine and Internet information, a combination that is changing how we can help our professionals take better care of us!!

I was hiking in the deep woods, of Chester, South Carolina, the bush was thick. Sort of lost the trail and made do with a short cut. I came upon a deer stand, and looked around stop for a while. As I was sitting on the steps to the deer stand I notice a spider on my jeans, paying attention to the color. It was a cream color on the top side, long brown legs and a shape that made me think what kind was it, but that's when I decided to flick it off my knee cap. Well, apparently I didn't flick it far enough. It must have stayed on my jeans and I wasn't wearing any sock with my shoes (won't do that again). The spider crawled up my jeans and this time I felt the bite. Jumped up! Dam it hurt like the dickens, not like a bee or any other insect I had ever been bite by. At that time I didn't think it was a Brown Recluse, that was Sunday afternoon..... It wasn't until Monday at noon that I asked the nurse in my office to look at the bite and she told me to get to the doctors ASAP! I did that afternoon, my doctor told me it was a Brown Recluse bite, I said your shiting me! I told him that I had three other bite just like this one. He just smiled and gave me some medicine, I asked what kind, it was the kind they give to folks with leapers.

I when back to my office, a gal friend said these bites were serious and should look more into other treatments. I when home after work and wasted no time getting on the Internet to do homework, boy I'm so glad I did. What I found scared the hell out of me. The important thing was to get medical treatment in 72 hours, which I was getting, second was not to bust the blisters, that was to late for me. Third, was not to use soap and water, but to get some nitroglycerin spray and antibiotics from your doctor. This was recommended by a Dr. Richard Burton, who had written several papers on the treatment. I called the center for disease in Atlanta and found that the current medication was a treatment but wasn't the only one out there and none had been tested. So I when back to my doctor, after printing all the information on the subject and armed with this I was somehow going to convince this medical doctor that this was the treatment I wanted. It worked! To see a photo of my bites now you think it wasn't a Brown Recluse at all .... but it was! And that is the rest to the story...

The brown recluse spider is not common in Ohio. It is found mainly in the southern and Midwestern states especially Arkansas, Oklahoma and Missouri. To date, infested Ohio counties have had a history where this spider probably hitchhiked (shipped) into the home in furniture, appliances, storage cartons, boxes, old clothes and other household goods. The brown recluse spider is not aggressive. Most bitten people have directly contacted the spider when putting on clothing or shoes not used for long periods of time. They usually occur in houses on the floor or behind furniture (undisturbed areas).

Some have been bitten after sleeping in an unused bed after rolling over onto the spider or others after accidentally touching the spider when cleaning out undisturbed storage areas. Fatalities are rare, but bites are most dangerous to children, elderly and those in poor physical condition.

Identification

Adult brown recluse spiders are soft-bodied, yellowish-tan to dark brown, about 1/4 to 1/2 inch long and have long, delicate grayish to dark brown legs covered with short, dark hairs. The leg span is about the size of a half dollar. Distinguishing characteristics are the presence of three pairs of eyes arranged in a semicircle on the forepart of the head and a violin-shaped, dark marking immediately behind the semicircle of eyes with the neck of the violin pointing towards the bulbous abdomen.

The eight legs and violin marking appear on the flattened-like cephalothorax (combined area of the head and thorax). Both the male and female brown recluse spiders are similar in appearance and equally toxic. The immature stages closely resemble the adults except for size and a slightly lighter color.

Life Cycle and Habits

These spiders spin small, loose, white to off-white webs with irregular strands. The female lays eggs from May through August in off-white silken cases (sacs) about 1/3-inch in diameter. Sacs containing 40 or more eggs each are found hung in the web, overwinter in sheltered, dark areas and are guarded by the female until her death. Each female may lay as many as 300 eggs during her lifetime. Spiderlings emerge in 24 to 36 days leaving the egg case with slow development (10 to 12 months), and are influenced by weather conditions and food availability. Spiders can survive long periods of time without food or water and may live as long as two years.

This spider is most active at night when it comes out in search of food consisting of cockroaches and other small insects. During the day, time is spent in quiet, undisturbed places such as bathrooms, bedrooms, closets, basements and cellars. The spiders sometimes take shelter under furniture, appliances and carpets, behind baseboards and door facings, or in corners and crevices. Some have been found in stored clothing, old shoes, on the undersides of tables and chairs, and in folded bedding and undisturbed towels stored for long periods of time. Outdoors, the spider may be found in sheltered corners among debris, in wood piles, under loose bark and stones, in old barns, storage sheds and garages. These spiders are very adaptable and may be active in temperatures ranging from 45 to 110 deg F.

Bite Symptoms

The severity of a person's reaction to the bite depends on the amount of venom injected and individual sensitivity to it. Bite effects may be nothing at all, immediate or delayed. Some may not be aware of the bite for 2 to 8 hours, whereas others feel a stinging sensation usually followed by intense pain if there is a severe reaction. A small white blister usually rises at the bite site surrounded by a large congested and swollen area. Within 24 to 36 hours, a systemic reaction may occur with the victim characterized by restlessness, fever, chills, nausea, weakness and joint pain. The affected area enlarges, becomes inflamed and the tissue is hard to the touch. The spider's venom contains an enzyme that destroys cell membranes in the wound area with affected tissue gradually sloughing away, exposing underlying tissues. Within 24 hours, the bite site can erupt into a "volcano lesion" (a hole in the flesh due to damaged, gangrenous tissue).

The open wound may range from the size of an adult's thumbnail to the span of a hand. The sunken, ulcerating sore may heal slowly up to 6 to 8 weeks. Full recovery may take several months and scarring may remain. Plastic surgery and skin grafts are sometimes required.

First Aid

If bitten, remain calm, collect the spider, if possible, for positive identification and get medical attention immediately (contact your physician, hospital and/or Poison Information Center). Apply antiseptic solution to prevent infection and ice packs to relieve local swelling and pain directly to the bite area.

An effective antivenom is not generally available. The physician will usually administer high doses of cortisone-type hormones to combat hemolysis and other systemic complications. A report suggests that treatment with dapsone (a drug used mainly for leprosy) may reduce the degree of tissue damage.

Control Measures

The brown recluse spider is not aggressive and normally bites only when crushed, handled or disturbed. It is aptly named since it is a reclusive creature seeking and preferring seclusion.

Prevention

Shake out clothing and shoes before dressing, and inspect bedding and towels before using. People are most often bitten when putting on clothing that has hung undisturbed or shoes seldom worn, into which a spider has moved. Do not go barefoot or handle firewood without gloves.

Remove trash, old boxes, piles of lumber, old clothing and other unwanted items. Eliminate cluttered areas in basements, closets, attics and other outbuildings.

Dust and vacuum thoroughly and more frequently around windows, corners in rooms, under furniture, in storage areas and normally undisturbed places to eliminate spiders, webs and egg sacs. Use a dust mop, broom and dust pan, if needed.

Install screens on doors and windows to prevent entry. Seal or caulk cracks and crevices where spiders can enter the house. Wash off the outside of the house and roof eves.

Insecticides

Adult spiders spend little time in direct contact with surfaces. Instead, they are found in or on webbing. Thorough applications of fine particles of insecticides such as ULV, aerosols or fogs contact spiders in their webs causing quicker population reduction.

Use space sprays of pyrethrins or resmethrin for useful clean outs, especially attics and crawl spaces.

Thoroughly treat cracks and crevices of decorative molding, window and door trim and undersides of tables, chairs and shelves with residual pesticides. Use Diazinon, or propoxur (Baygon) as a long-lasting residual treatment.

Outdoors, spray around the perimeter of buildings using formulations that will not damage plants. Treat under eaves, patios and decks if the house is of pier and beam construction. Baygon, Diazinon and permethrin are frequently used.

There are many other labeled pesticides for spider control. Some are labeled for homeowner use, while others are labeled only for the licensed, certified, pesticide applicator or pest control operator. Homeowners can use amorphous silica gel (Drione, Tri-Die), some formulations of bendiocarb (Ficam), chlorpyrifos (Dursban), and permethrin (Astro, Dragnet, Flee, Prelude, Torpedo); diazinon, esfenvalerate (Conquer), propoxur (Baygon), pyrethrin (Exciter, Kicker, Microcare, Pyrethrum, Safer, Synerold, Uld, X-Clude) plus resmethrin (Vectrin). In addition, the licensed pesticide applicator can use bendiocarb + pyrethrins (Ficam Plus), clyfluthrin (Optem, Tempo), cypermethrin (Cyper-Active, Cynoff, Demon, Vikor), deltamethrin (Delta Dust, Suspend), lambdacyhalothrin (Commodore), propetamphos (Safrotin) and tralmoethrin (Saga).

Before using any pesticide, always read the label and follow directions and safety precautions.

Hey! A Brown Recluse Spider Bit Me!

What a brown recluse spider is:
The brown recluse spider is one of six venemous kinds of spiders in the United States. It is part of the arachnid family, which includes not just spiders, but ticks, mites, and scorpions, too. It has long, skinny legs and is about one-half inch long overall. Its entire body is brown, except for a dark mark in the shape of a violin on its head. Its venemous relatives may be gray, orange, reddish-brown, or pale brown.

Brown recluse spiders are most commonly found in Midwestern and Southern states of the U.S., and they usually hang out in dark places. When they are outside, they like to spend time in piles of rocks, wood, or leaves. If they come inside, brown recluse spiders will go to dark closets, attics, or basements. They are non-aggressive and bite only when disturbed.

What a brown recluse spider bite looks and feels like:
A person who gets bitten by a brown recluse spider may not notice anything at first or only feel a little sting at first. After about four to eight hours, the sting will start to hurt a little more. It might look like a bruise or might form a blister surrounded by a bluish-purple area.

What you should do:
If you ever think that you've been bitten by a brown recluse spider, tell an adult immediately. Brown recluse spider bites rarely kill people, but it's important to get medical attention as soon as you can because they can make you pretty sick. With an adult's help, wash the bite well with soap and water. You can also apply ice to the area, elevate it, and keep it still. If it's possible, have an adult catch and bring the spider to the doctor's office with you - this is important because it can sometimes be hard to diagnose a spider bite correctly. The spider can be killed first before you bring it with you; just be sure not to squish it so much that no one can tell what it is.

What a doctor will do:
Doctors treat people who have been bitten by a brown recluse spider with different types of medications like antibiotics, antihistamines, steroids, and pain medicines. Sometimes a skin graft might be needed if the skin is really damaged at the area of the bite. (A skin graft is when a small amount of skin is removed from some part of the body and put in a place where skin is damaged to create new skin.)

How to avoid getting bitten:
The best way to avoid getting bitten by brown recluse spiders is to be careful in areas where they like to spend time. Don't play around in rock piles or wood piles. If you are working outside in the yard in big piles of logs or leaves, wear gloves. Be sure to shake out blankets and clothing that have been stored in the attic or the basement, or if they have been in a closet but not used for a long time. If you keep your shoes in a mudroom or garage, shake them out before putting them on.
