Part 1 of Recognize a black widow spider. Black widow spiders are found across the U. S and Canada, and in other temperate regions around the world.
They are the most venomous spiders in North America. The female is the easiest to recognize -- and the most dangerous. She is coal-black, with a spherical abdomen and a red hourglass-shaped mark on her belly. Her body is approximately half an inch long, but she has a total length of 1. The male is about half the size of the female and is brown or grey. He usually has several red dots on his abdomen and may have a yellow or red band across his back.
Male black widow spiders are not venomous. Young black widows, known as spiderlings, are white or yellow-white when they first hatch.
They become darker as they grow. They may have yellow or red patches across their backs, resembling the adult male. It is impossible to tell male and female spiderlings apart.
At this stage, both are harmless to humans. Know its habits. The black widow spider is timid and reclusive, preferring to make its home in dark, protected areas, such as in boxes, among firewood and under ledges. It is nocturnal, actively hunting at night. The black widow spider's web is usually located within a foot of the ground.
It is slightly erratic in appearance and made with stronger silk than most other spider webs. The web is used to catch prey and to hang the female's cocoon of eggs. Black widows are usually found in dark corners of the house or around the edges of a yard or garage where their webs will have a lesser chance of being disturbed. They may also be found under vehicles, even those that are being driven periodically.
Black Widows are territorial, so their webs are often spaced about a foot apart. Understand the dangers. Female Black Widow spiders have very powerful venom -- in fact, it is said to be15 times stronger than that of a rattlesnake.
The venom is a neurotoxin. Symptoms include muscle aches, abdominal pain, breathing difficulties and nausea. The majority of Black Widow bites are easily treated. However, if medical treatment cannot be administered on time, a Black Widow bite can lead to convulsions and death. Black Widow spiders are not aggressive and will only bite as a defense mechanism. Most bites occur when the spider is accidentally disturbed or injured, and feels threatened.
Small children, the elderly and the infirm are much more susceptible to adverse reactions when bitten by a Black Widow. Medical treatment should be sought immediately. Watch out for Brown Recluse spiders too. Another venomous spider which is slightly more common than the Black Widow is the Brown Recluse spider.
These are harder to identify because they look like many other spider species, ranging in color from dark cream to brown. They are similar in size to the black widow and have a dark violin shaped mark on their back. The venom of the Brown Recluse spider is not as strong as the Black Widow's, but their bite can lead to death. The methods for getting rid of Brown Recluse spiders are the same as for the Black Widow, so you can target both species at once. Part 2 of Locate as many spider webs as you can during the day.
Black Widow spiders are nocturnal, so they are inactive during the day. Daytime is the best time to locate all existing webs, so you can come back and kill the spiders once darkness falls. Look for the webs in dark, sheltered areas that are usually left undisturbed. Indoors, look for webs in dark corners of closets, under the bed and in cluttered areas of the basement and attic. Outdoors, look for the webs under window ledges and door frames, in piles of firewood or stacked lumber and in close-growing vegetation.
Black Widow webs are disorganized and erratic looking. They are slightly funnel-shaped, giving the female Black widow a convenient place to hide during the day. Never intentionally disturb a web without protective clothing and a method of killing the spider.
Make a note of the location of each web, so you will be able to return to it later. Try using dust applications and liquid spot treatments. Once you know the locations of the webs, there are a couple of things you can try to eliminate the spiders without actively killing them.
Get your hands on a dust or liquid insecticide which you can spray or sprinkle on the webs and surrounding areas. These will kill the existing spiders upon contact, while also preventing new spiders from moving in.
Dust applications are best for out-of-the-way places where the dust won't be disturbed by anyone but the spiders. This includes attics, basements and crawl spaces. It can also be applied to wall voids, using a hand duster. Liquid spot treatments are usually purchased in powder form, which is then mixed with water to form a residual spray.
This works best under and behind furniture, under beds, in storage spaces and any dark corners. Even though these products are very effective, they are not guaranteed to kill all of the spiders, so they are best used in combination with more active methods of elimination and to prevent new spiders from coming back.
Return to the webs at night to kill the spiders. The most surefire way to kill the Black Widow spiders is to return to their webs at night -- armed with your weapon of choice -- and eliminate them yourself. It doesn't have to be the middle of the night, once the sun sets the spiders will be active and easy to find. Make sure to bring a powerful flashlight and to wear protective clothing, such as thick gloves and boots, as the spiders can be very quick when under threat and you want to expose as little skin as possible.
Here are the best methods of killing the spiders: Kill the spiders with insecticide. Using a non-residual spray insecticide is one of the quickest and easiest ways of killing Black Widow spiders.
The spray must come in direct contact with the live spider, at which point it will quickly stun and kill it. These sprays are safe to use and will not leave harmful residues behind.
