Before working in the lawn care field, I worked on an ambulance as an EMT for the state of Indiana. We were taught about spiders. There are two kinds to worry about in the US. Black widows and brown recluse.
BROWN RECLUSE:
Dull brown in color, smaller than black widow. Has a dark violin-shaped mark on it's back. Mostly found in the Southern and Central US, but moving to other areas of the US. They live in dark areas, corners, unused buildings, woodpiles, under rocks, etc. Bite area not painful at the time of the bite. There should be no vomiting, nausea, breathing difficulty, or other problems that are common with black widow bites. The bitten area will beome red, swollen, and tender. It will develop a pale, white/bluish center. A small blister may form. Then the ulser develops. Quick treatment from a doctor can keep the patient from developing the ulser.
BLACK WIDOW:
These are not large spiders, approx. 1 inch long with legs extended. It is a glossy black and has a bright red-orange marking in the shape of an hourglass on it's abdomen. They are found in every state except Alaska. They prefer dry, dim places around buildings, in woodpiles, and among debris. This type of bite is sometimes overlooked because the victim may not recall the bite because the area may become numb after the bite. Usually, though, there is pain at the area of the bite. The venom is poison to nerve tissue and attacks the spinal nerve centers. The symptoms are:severe cramps, tightness in the chest, breathing difficulty over the first 24 hours. Dizziness, sweating, vomiting, nausea, skin rashes also occur.
Death is not common. These bites are more dangerous to children or elderly.
This bite is very painful. If the site of the bite can be identified, apply ice to this area. Get the person to the Emergency Room as soon as possible.
If you kill the spider, it is useful to bring it to the Emergency Room with you. This goes for snakes, too, if you ever need snake bite treatment. Do not endanger yourself further by trying to catch it.
I hope this helps you guys. Sorry it's a long post, just thought you might be interested.
STAY SAFE!
