Eliminate as much clutter as possible in storage areas and frequently dust and vacumn around windows, corners of rooms, and under furniture.
Trim weeds around the building foundation and remove debris to discourage insects and spiders from living next to a structure.
Seal openings and install screens and door sweeps to prevent spiders (as well as other unwanted pests) from moving indoors.
Use a vacuum cleaner to remove webs, spiders and their egg sacs.

Recommended products for black widow spiders are:
Cyzmic CS, or Cyper WP sprayed around the foundation, window frames, door frames, soffit areas, vent openings, exhaust areas, garages, basements, mounted lights, air conditioning areas, cable entry points, deck areas, stoop and patio areas.
It would be helpful to spray a liquid barrier with Demon or Cyper WP 5-10 feet out, which will work against any black widow spiders trying to enter by the ground level .

Dusting is useful if there are voids such as electric outlets, switch plate covers or vent areas where spiders are emerging.

Using a bulb duster like Bellows duster, would allow for easier dusting.

Black Widow Spiders are considered venomous spiders in North America.
Black Widow spiders are not usually deadly, especially to adults, because they inject only a small amount of venom.
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.
After mating, the female sometimes eats the male, earning the name "widow."

How to Identify Black Widow Spiders

FEMALE BLACK WIDOW

The female black widow spider is the most easily recognized, her shiny black body giving great contrast to the red hourglass marking on her round abdomen.

Adult black widow spider males are harmless, about half the female's size, and usually have yellow and red bands with spots on their backs.

The legs of the male are much longer in proportion to his body than that of the female, with it's body half the size.

Black Widow Spider Habits

Black widow spiders can be found around wood piles, and are frequently encountered when homeowners carry firewood into the house.
Webs are usually built near the ground (occasionally within dwellings) normally in trash, rubble piles, under or around houses and outbuildings such as privies, sheds and garages.
They can be found under eaves, in storage bins, underneath unused construction materials, inside wooden toy boxes, firewood boxes, outdoor toilets and sheds, meter boxes, and other undisturbed places.
Black widow spiders can be found on the underside of ledges, rocks, plants and debris, wherever a web can be strung.
Cold weather and drought may drive these spiders into buildings.

The female black widow spider rarely leaves her web,and retreats waiting for her prey.
The web she constructs is an irregular, tangled, criss-cross web of rather coarse silk. They can be found under stones, outside boards, along foundational slabs, behind shrubs, and along sliding that touches the ground.

This same web may be rebuilt or changed on an ongoing basis depending upon her needs.
This female spider spends most of her daylight hours there.
She is often found hanging upside down.

The female captures her victims with her silk, wrapping it around the prey .
After the covering of the silk, the prey is killed by an injection of venom.
The prey might be eaten immediately or reserved for a later feeding.

She stays close to her egg mass, defensively biting anything that disturbs her or her egg sac.
Egg sacs are oval, brown, papery and about ½ inch long. They hold from 25 to 750 or more eggs, which have an incubation period of 20 days.

Newly hatched spiders are predominately white or yellowish-white, gradually acquiring more black and varying amounts of red and white with each molt.
Growth requires two to three months, with older black widow spider females dying in autumn after egg laying.

The female black widow stores sperm, producing more egg sacs without mating.
Some black widow spider females live more than three years.

Black Widow Distribution

The black widow spider’s range is from Massachusetts to Florida and west to California, Texas, Oklahoma and Kansas.

Although they can be found in almost every state (and some portions of Canada), this spider is most common in the Southern areas of the United States.

Black Widow Spider Bites

The venom in the black widow bite is toxic to the nervous system. There are many variables to a person's reaction to a bite. The severity may depend on the body weight, the person's general sensitivity, where the bite occurred, the amount of venom that was injected, depth of bite, ect.

You may not always feel the black widow spider bite at first.

The first sign of a bite is a small local swelling.

There may be two small red spots in the center of the swelling.

After three hours or so, the site of the bite becomes more painful.

Common reactions include an overall ache of the body, in particular the legs.

Other symptoms include alternating salivation and dry-mouth, paralysis of the diaphragm, profuse sweating and swollen eyelids.

In severe cases, a headache, elevated blood pressure, nausea and perspiration could occur.

The poison injected by the Black Widow Spiders bite can cause abdominal pain similar to appendicitis as well as pain to muscles or the soles of the feet.

In most cases symptoms disappear in two or three days.

Calcium gluconate is used intravenously to relieve and relax muscle spasms produced by black widow venom.

The victim of a black widow bite should go to the doctor immediately for treatment

Clean the site of the bite well with soap and water.
Apply a cool compress over the bite location and keep the affected limb elevated to about heart level.
Aspirin or Tylenol may be used to relieve minor symptoms.
Treatment in a medical facility may be necessary for children less than 5 years old or for adults with severe symptoms.

Take proper precautions, wear gloves and pay attention to where you are working.
