1. Spider -- Brown Recluse Spider
   Spider traps are most effective at reducing Brown Recluse populations from these locations your home. By setting traps, it can be determined whether or not a home has Brown Recluse spiders.
2. Spider -- Hobo Spider
   Note: A Hobo spider (Tegenaria agrestis) can cause the same symptoms as the BRS. They are spreading in the NW states, apparently starting in Seattle around 1930. It is possible that some bites reported in this region, resulting in necrotic arachnidism, may stem from the Hobo, not the BRS.
3. Spider -- Black Widow Spider
   A black widow spider bite gives the appearance of a target, with a pale area surrounded by a red ring. Severe muscle pain and cramps may develop in the first two hours. Severe cramps are usually first felt in the back, shoulders, abdomen and thighs. Other symptoms include weakness, sweating, headache, anxiety, itching, nausea, vomiting, difficult breathing and increased blood pressure. Young children, the elderly and those with high blood pressure are at highest risk of developing symptoms from a black widow spider bite.
4. Spiders -- Black Widow Spiders
   Be very careful when working around areas where black widow spiders may be established. Take proper precautions - wear gloves and pay attention to where you are working. The reaction to a Black Widow bite can be painful. The victim should go to the doctor immediately for treatment.
5. Spiders -- Houses
   Many spiders may only live for about a year, but a number will live two years or more, overwintering in sheltered areas. The annual influx of 'outdoor' spiders into houses in the fall is due to this search for a warm place to spend the winter. It is common for female tarantulas to live up to twenty years.
6. Spiders -- People
   Have you seen this picture and read the usual accompanying story about "camel spiders" or "Fallujah spiders" in Iraq that anesthetize and eat people alive? This is a hoax. The arachnids in the picture are not spiders, they are solpugids and they have no venom. They eat roly-poly bugs, crickets, and scorpions. And they aren't just in Iraq; they are found in deserts. There are some in the southwest U.S. Also, notice that the picture was taken to make these arachnids look bigger.
7. Spider -- Species
   The presence of a violin-like marking on the back of a spider is not conclusive evidence of a brown recluse spider. There are other species of spiders which have markings that resemble violins.The brown recluse spider does not have any markings on its abdomen. If you see a spider that has markings on its tail end, it cannot be a brown recluse spider.The color of the abdomen is tan to brown, but may appear darker if the spider has recently fed.
8. Spiders -- Bodies
   Spiders are fairly tolerant of environmental extremes. They can adjust their body temperatures to be higher or lower than the ambient temperature by, for example, sunning to warm up, or by escaping into the shade or a burrow to cool down. High body temperatures threaten the loss of water as vapor through transpiration; a loss amounting to over 20 percent of the spider’s body weight is lethal. Spiders can drink, even from moist soil. Many spiders are nocturnal, which means that they are active only during the cooler, more humid parts of the day. Spiders can survive cold winter temperatures by moving to relatively warm micro-climates such as burrows or leaf litter; they curl up to reduce exposure, become rigid and reduce their meta-bolic rate.
9. Spiders -- Insects
   Spiders can be their own enemies. Many young spiders do not hatch or live long because they are eaten by their brothers or sisters, a habit known as cannibalism. Enemies of spiders include birds, reptiles, mice and other small mammals, and certain insects. Mud dauber wasps and other sphecids use spiders as a source of prey. The wasp family Pompilidae, commonly known as spider wasps, prey only on spiders, and some will attack large tarantulas. Parasites of spiders include ichneumon wasps and some flies.
10. Spider -- Markings
    Spider processes all the regular expressions in the order shown in this window, starting with the pre-compiled regular expressions, then the user-supplied ones. (The pre-compiled expressions are considerably faster than user-supplied ones, which are compiled at run-time.) The first successful match found in a file causes Spider to cease processing the file, close it, and add it to the list in the log file.
