   Extractions: Spider Venom All spiders, with the exception of two very small families, have poison glands. The spider’s venom is used to kill their pray. All spiders are exclusively carnivorous and generally prey only on live animals. Spiders chiefly dine on insects. Preying on mosquitoes, for example, makes the spider beneficial in the control of mosquito-borne disease such as encephalitis. Some spider species are used to help control insects from destroying grain crops such as wheat. Spiders use their venom as a means to gain food and for defense. The vast majority of spiders do not produce venom virulent enough to harm humans. Too, spiders are timid creatures and bite and inject venom only in self-defense. Most spiders will run away as fast as they can, however, if felt cornered or in the protection of their young, they will bit humans.

   Extractions: Contact: Eric Day, Manager, Insect Identification Laboratory August 1996 Araneae: Theridiidae, Latrodectus mactans SIZE: About 1 1/2 inches (38mm) long, 1/4 inch (6.4mm) in diameter COLOR: Usually shiny black DESCRIPTION: The female is usually black with a red spot or hourglass- shaped mark on its round abdomen. The male usually has light streaks on its abdomen. HABITAT: Black widow spiders are common around wood piles, and are frequently encountered when homeowners carry firewood into the house. Also found under eaves, in boxes, outdoor toilets, meter boxes, and other unbothered places. TYPE OF DAMAGE: The black widow is not aggressive. It will, however, bite instinctively when touched or pressed. CONTROL: 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. Black widow bites are sharp and painful, and the victim should go to the doctor immediately for treatment. To control the black widow, carefully remove all materials where they might hide. They can be cleaned out of an area simply by knocking down the webs, spiders, and round tan egg sacs with a stick and crushing them underfoot. INTERESTING FACTS: The female eats the male after mating. She hangs belly upward and rarely leaves the web.

   Extractions: Eggs of widow spiders are laid in an egg sack, attached to the web of the mother. The sack is pear shaped, and creamy yellow, light gray, or light brown in color. About 200 eggs may be laid in an egg sack and females may produce several egg sacks if conditions are favorable. Where do you find black widows? Widow spiders prefer to nest near the ground, in dark, undisturbed areas. Nest sites often are near holes produced by small animals, or around construction openings and wood piles. Low shrubs also are common sites for widows to occur. Indoors, widows similarly occur in dark, undisturbed sites such as behind furniture or under desks. Undisturbed basement areas and crawl spaces of homes are also used by nesting widow spiders. What are the symptoms of poisoning by widow spiders?

   Extractions: Items ... www.kill-fireants.com Black Widow Spider BIOLOGY OF SPIDERS SPIDER ELIMINATION Araneae: Theridiidae, Latrodectus mactans The female black widow spider rarely leaves her web. The web she constructs is an irregular, tangled, cris Egg sacs are pear shaped (or oval), brown, papery and about ½ inch long. They hold from 25 to 900 or more eggs, which have an incubation period of 20 days. The spiderlings disperse shortly after emerging, tearing an opening in the egg sac and stay near the sac. After several hours, these second instar spiderlings balloon to the ground and scatter. Growth requires two to three months, with older females dying in autumn after egg laying. Of all spiders, the Black Widow is the most feared. The female’s venom is especially poisonous to people. Despite its reputation, this spider often attempts to escape rather than bite, unless it is guarding an egg mass or if it is cornered and pressed. The male black widow will not bite you. After mating, the female sometimes eats the male (remember, she only has to mate once in her life), earning the name "widow." During the period shortly following mating and laying of eggs, the female black widow can be a little cranky and hungry. After this period (if he lives through it!) the male lives quite comfortably, eating prey captured by the female. The development of his venom sacs stop and become inactive as the male matures, thus making him less of a potential problem than his female counterpart.

   Extractions: The female hangs upside down in the web such that the red hourglass faces up. The egg sacs, which contain up to several hundred eggs, are most frequently encountered from May to October. The female typically stays with and guards the sac until the eggs hatch. The young spiderlings remain inside the sac for several days subsequent to hatching. Within a few days after emergence, the spiderlings release strands of silk out into the breeze and are carried off into a new territory. Most of these flights occur during the early fall months. Development from egg to adult may take from two to four months or more. A female may live a year or more after maturity. Males are sometimes killed by the female soon after mating, thus the name "widow" is attached to the spider

   Extractions: INTRODUCTION: These spiders get their common name from the popular belief that the female eats the male after mating, a phenomenon which rarely happens in nature. The genus Latrodectus is worldwide in distribution, with 5 species occurring in the United States. Recognition of the genus is sufficient for PCO purposes. RECOGNITION: Young spiders primarily orange and white but acquire more and more black as they mature, with markings very similar to those of males. With 1 or 2 reddish markings on underneath side of abdomen. REPRESENTATIVE SPECIES: Identification to species is left to experts since several species are involved and species separation is based primarily on differences in the male gentalia. Although a very brief description based on female coloration is given below, it must be realized that color and markings are not always reliable characteristics for separation of these species and that males are usually colored and marked quite differently. 1. Latrodectus bishopi Kaston, the red widow. Cephalothorax reddish, abdomen black with reddish to organish spots outlined by white, red marks on venter, and legs reddish; occurs only in central and southern Florida. 2. Latrodectus geometicus (Fabricius), the brown widow. Color brownish with white and black brown markings, abdomen with red hourglass mark, legs banded/ringed; occurs only in southern Florida.

    Extractions: William F. Lyon Common Name Scientific Name Black Widow Spider Latrodectus mactans (Fabricius) Northern Widow Spider Latrodectus variolus (Walckenaer) Both the black widow spider and northern widow spider are present in Ohio. The black widow spider is found primarily in the southern Ohio counties whereas the northern widow spider is found in the northern Ohio counties. Most occur outdoors and are not aggressive unless confined or disturbed. Females are more likely to bite when guarding an egg sac. Reports indicate that mortality from bites is the result of one percent or less of the cases, usually occurring in very young or very old individuals. With healthy people, recovery is usually complete in 2 to 5 days. However, this spider is considered the most venomous spider in North America. Adult black widow spiders have shiny, jet black, rounded, globular abdomens with two reddish or yellowish triangles on the underside which form a characteristic hourglass marking. Adult female northern widow spiders are shiny black or brown-black with two reddish triangles on the underside, resembling a split hourglass. These spiders are about 1/2-inch long, not including the legs (about 1-1/2 inches when legs are spread). Adult males are harmless, about half the female's size, with smaller bodies, longer legs and usually have yellow and red bands and spots over the back as do the immature stages. Newly hatched spiderlings are predominately white or yellowish-white, gradually acquiring more black and varying amounts of red and white with each molt. Juveniles of both sexes resemble the male and are harmless.

    Extractions: Newly hatched black widows are white with black spots on their abdomens with a cream colored hourglass. Later as they mature they become cream and brown-striped. The black widow requires about 4 months from egg to maturity with the females going through six to nine molts. Over their one to two year life span the females produce several egg sacs, each containing several hundred eggs. Female black widows guard the sac, which resembles a silken cocoon, until the eggs hatch. During this time she is most likely to bite when threatened. Eggs are most frequently encountered from May to October.

    Extractions: From: R.L. Smith, 1982. Venomous Animals of Arizona. The University of Arizona. Warning: The bite of a "black widow" spider can be life-threatening. If you or someone in your care has been bitten by a "black widow" spider, obtain professional medical assistance as soon as possible. No emergency first aid procedures are recommended for "black widow" spider bites (see first aid instructions Description: The common name black widow spider specifically belongs to the eastern species Latrodectus mactans , which does not occur in Arizona. Latrodectus hesperus , our species, is very similar to the true black widow. The adult female has a shiny black (occasionally dark brown) body approximately 1.5 cm long and slim black legs with a span of about 4 cm. The most famous and easily distinguishable characteristic of this species is the bright red hourglass-shaped marking on the underside of the bulbous female abdomen (Figure 11). Immature females have red, brown, and cream-colored markings on the dorsal surface of the abdomen (Figure 12), and a cream-colored hourglass. Males are much smaller than adult females (about 1/20 the size) and, like immature females, are patterned with red, brown, and cream (Figure 13).

    Extractions: Black Widow Spiders are extremely poisonous arachnids (not insects). Their venom is 15 times as poisonous as the venom of the prairie rattlesnake . These venomous spiders are found in warm and temperate climates all around the world. They live in dark places, in drain pipes, under logs and rocks, etc. in North America from Florida and California to southern Canada. Their bite rarely kills humans. The female will sometimes eat the smaller male after mating. She will lay 300-400 eggs. The spiderlings (baby spiders) are not poisonous but they are cannibals, eating each other. Diet : Black Widows eat flies, moths, crickets, small reptiles and other small animals. Their fangs inject venom and digestive juices into the prey. This kills the prey and also liquifies its flesh, letting the spider eat it easily. Anatomy : Females (about 1 1/2 inches across) have a black body with a distinctive red hourglass shape on the underside of the abdomen. Males are smaller (about 3/4 inch across) with longer legs and red and yellow markings. The females are much more poisonous than the males. Black Widows have a two-part body, strong jaws, poisonous fangs, and a hard exoskeleton. Webs : Black Widow Spiders use silk to make tangled-looking webs, usually near the ground in dark places. The tips of the spider's legs are oily; this oil keeps them from getting trapped in their own webs.

    Extractions: glossy black. The underside of the abdomen has a distinct red or orange hourglass shape in the southern black widow. Males and immatures have similar markings. Immature individuals are orange and white and will become more black with each molt (Lacy 1997). The markings on the underside of the immature's abdomen may be red and are variable in shape and often not joined (Lacy 1997). Males have whitish markings (streaks, bars or dots) on the top side of the abdomen and red triangular markings on the underside. In the northern black widow, the hourglass appears split in the middle. The northern widow has a row of red spots along the central, top of the abdomen (Hedges and Lacy 1995). The southern black widow prefers dark, sheltered areas. In nature, they construct their webs in hollow logs and under loose bark or stones, in small trees and under bushes. Man has provided additional suitable habitat in the form of crawl spaces under houses, firewood piles, under boards, under furniture, inside boxes, seldom worn shoes, behind and under debris, drainage pipes, false ceiling areas, out-houses, sheds, barns, well houses and root cellars. Northern black widows tend to make their webs in the branches of trees.

    Extractions: Feel free to call 1-800-476-3368 if you have any questions! Spiders are considered a beneficial insect because of their prey to other insects. However their are two North American species that are dangerous to humans: Black Widow and Brown Recluse. Most spiders are harmless, but we do include recommended treatment and products at the end of the section. BLACK WIDOW The female has a shiny black, globular abdomen with two yellow or red markings in a triangle shape. It looks like a hourglass. Males are smaller, lighter in color, with light streaks on the abdomen. The web is irregular, many times found along exterior foundations on slabs, under stones and rocks, behind shrubs .They usually don't into structures .They will bite if provoked. The bite feels like a sharp pain ,like a needle puncture. After 15 minutes to an hour there will be muscular cramps. Bites are rarely fatal, but you should seek medical attention.

    Extractions: Salutations! , and welcome to my "web" site. As you can see, I have a passion for this "Black Beauty" which started at the age of 10 when my father caught and housed a female black widow spider. Over that summer, we watched her spin and repair her nest with such care, hunting her prey, and even had the opportunity to witness first hand the dance of the mating ritual. As you move through my site, reading about the beautiful, black widow spider, viewing the gallery and its many photos, I hope you'll come to understand and possibly share in my appreciation for this magnificent instrument of nature. I'll strive to make this site informative, fun and a bit personal, while we take a journey together and learn more about the stunning Black Widow spider. Educational Resources

Stronger and more flexible than steel, spider silk offers a lightweight alternative to carbon fibre. Up to now it has been impossible to produce "spider fibre" on a commercial scale. Unlike silk worms, spiders are too anti-social to farm successfully. Now a Canadian company claims to be on the verge of producing unlimited quantities of spider silk - in goat's milk. Using techniques similar to those used to produce Dolly the sheep, scientists at Nexia Biotechnologies in Quebec have bred goats with spider genes.
