Black widows are a dangerous type of spider that is found throughout the United States. In fact, Alaska stands as the singular state without any of these venomous spiders. However, even though every state in the Lower 48 and Hawaii have a population of black widows, they are much more likely to be seen in some states as opposed to others. Because they prefer warm climates, you are most likely to encounter black widows in the southern and southwestern portions of the country.

Although a accurate head count of the number of black widow spiders residing in each state does not exist, many point to Texas as likely having the highest population — or at least being near the top of the list. This is primarily because much of the Lone Star State consists of ideal black widow habitat. It is also partially due to the fact Texas is known to be the state with most types of venomous spiders, with nearly a dozen different types of dangerous arachnids being found there. Among those are 3 separate strains of black widows – southern, northern, and western – as well as brown widows.

Other states that are known to have a high black widow population include California and Florida. However, they are found in fairly significant numbers across the southern half of the country, including in some harsh desert environments such as those found in New Mexico and Arizona. Hawaii, with its warm year around weather, is another state with rampant numbers of black widows. Ironically, however, black widows were not native to the islands, but rather introduced there by accident.

Given that black widows are capable of delivering a bite that requires immediate medical attention, you certainly want to do your best to avoid them. However, there are precautions you can take to steer clear of black widows.

For the most part, know that you won't encounter black widows out in the open. Outside, they favor dark areas like piles of wood, underbrush, or rocks. So when hiking, camping, or otherwise adventuring outdoors, wear long sleeves and gloves when handling wood, and don't put your hands somewhere without first checking the area for spiders. Additionally, you should always shake out clothing, sleeping bags, and shoes before utilizing them. An insect repellent containing DEET, such as Repel Sportsmen Max, can help deter black widows.

Keep in mind, black widows are found in yards and homes as well. So follow those same precautions when moving firewood or brush in your yard. Indoors, black widows are likely to be found in piles of clutter in attics, garages, or sheds. As a result, it is best to keep clutter to a minimum and exercise caution when moving through piles or stacks of stuff, even in the house. If you are bitten, immediately wash the area and apply ice. Keep the bite area elevated and seek medical attention.
