A Guide To Black Widow Spider Control For Dallas Property Owners

Spider populations almost always accompany larger pest problems. Some spider infestations are worse than others, like the kind that results in painful bites that require medical attention. Black widows, a common invasive spider variety, can pose greater risks to your health and property than simple house spiders. Learning more about how to spot and deter them is crucial for prevention.

What Even Are Black Widow Spiders?

Black widows are one of the most poisonous spiders in North America, but they aren’t often seen by humans. They are solitary predators that stick to the shadows and tend to be nocturnal hunters. As such, many people don’t actually know what they look like:


Black widows aren’t tarantula-sized, but they are usually larger than typical house varieties. Including leg span, black widows can grow to around an inch in diameter.


Black widows are inky dark, with the sole splash of color being the telltale crimson hourglass found on their bellies.


Black widows nest in woody, dark areas, so you’ll typically only find their nesting grounds in piles or undersides of porches and roofs. Their feeding webs, however, can be just about anywhere, a headache for those who like to do clean sweeps for webs.

Dangerous (But Rare) Bites

The biggest problem with a black widow infestation is obviously their bites. These are far more serious than the common bug bite. While black widow bites themselves are rare and almost never lethal, you don’t want to have to judge for yourself how dangerous a bite is.

If you or a loved one suffers a bite or exhibits any of these common symptoms, you should seek medical attention immediately:

Pain & Swelling

Like all bites, the area of puncture will swell and pucker, often with an itchy burning sensation. Black widow bites are often much more painful than other bites.

Nausea & Dizziness

The effects of a black widow bite are more assailing to our bodies than less venomous pests. It’s not uncommon for people to feel light-headed and sick following a black widow bite.

Muscle Spasms

The purpose of black widow venom is to paralyze prey, as such it can have direct effects on our muscular system as well.

Spider Prevention For Your Property

Not only do you need to take steps to prevent black widows themselves, but you need to prevent the critters that they prey upon, too. The presence of other pests can drive spiders, including black widows, onto your property:

Food Storage

Spiders hunt for their own food, but the bugs they prey upon will forage for scraps and traces. You have to eliminate these sources in order to curb pest populations.

Wood Storage

Black widows will often find their way into structures thanks to wood piles or materials stacked too close to the building. Keep these things well away from your home or business to reduce the likelihood that nests will be nearby.


Seasonal or year-round treatments for your lawn and exterior can help ward off all kinds of pests, including black widows. Since most infestations start outdoors, yard protection is a necessity.
