Brown Recluse Spider
The brown recluse spider is also known as the fiddleback spider because of its brown color and violin-shaped thorax. It is one of the most venomous spiders in North America. The venom is cytotoxic, which means that it destroys cells, tissues, and organs and causes a range of symptoms.
Appearance: The brown recluse spider has a light brown color and a dark mark on its back, which is often described as a violin or fiddle shape. The spider is approximately 0.5 inch long and has long, thin legs. Its body is covered with short hairs, and it has six eyes arranged in pairs.
Habitat: The brown recluse spider is commonly found in the south-central and Midwestern United States. It prefers warm, dry environments and can be found in dark, undisturbed areas such as closets, basements, and attics.
Bite symptoms: The brown recluse spider bite can be painless or cause a mild stinging sensation followed by intense pain. The bite site may become red and swollen and may develop a bullseye pattern. The venom can cause necrosis (tissue death) which can lead to an open ulcer that oozes fluid and forms a scab, which can take longer than six weeks to heal. Brown recluse spider bites can also cause fever, chills, muscle aches, and nausea.
Treatment: If bitten by a brown recluse spider, seek medical attention immediately. The wound should be cleaned and a tetanus shot may be necessary. Treatment may include pain management, antibiotics to prevent infection, and in some cases, surgery to remove dead tissue.
Prevention: To prevent brown recluse spider bites, it is important to keep living and workspaces neat and organized, as they prefer undisturbed areas. Wear protective clothing when handling boxes or working in attics and basements. If you suspect a brown recluse spider infestation, contact a licensed pest control operator.
While both the black widow and brown recluse spiders are venomous and potentially harmful to humans, it is important to understand the differences in their appearance, habitat, bite symptoms, and treatment. If you come in contact with either of these spiders, seek medical attention immediately.
Habitat
The habitat of the Black Widow Spider and the Brown Recluse Spider differs in certain aspects. Black Widow Spiders are commonly found in warm climates such as the southern and western parts of the United States, while Brown Recluse Spiders are primarily found in the central and southeastern parts of the country. Black Widow Spiders usually prefer areas that are dark and hidden, such as wood piles, sheds, and garages, while Brown Recluse Spiders tend to hide in dark and quiet places, such as closets, attics, and basements.
Black Widow Spiders are also known to make their webs in outdoor areas such as around bushes, trees, and rocks. These spiders prefer to build their webs at a height of around 3-8 feet above the ground. Interestingly, Black Widow Spiders may build several webs if the old one becomes damaged or infested with parasites.
On the other hand, Brown Recluse Spiders often build their irregular webs in undisturbed areas such as cluttered and dark corners. It’s common for them to inhabit stacks of boxes, under furniture, and inside clothing left on the floor. Since Brown Recluse Spiders are primarily nocturnal, they usually come out at night to search for prey or when disturbed by movement near their hiding places.
It’s also worth noting that both these spiders can be found in outdoor and indoor areas such as barns, outside restrooms, and storage buildings. It’s important to be cautious and keep an eye out when venturing into any of these areas.
Understanding the habitat of these spiders can help individuals take preventive measures, such as not leaving clothes or shoes on the floor, storing items in plastic containers, and wearing protective clothing when gardening or handling firewood in outdoor areas. By taking necessary precautions, individuals can decrease their chances of encountering these venomous spiders and avoid the harmful effects of their bites.
