Brown Recluse Spiders: Things They Should’ve Told You About At School

Brown Recluse Spiders

This species of spiders are not peculiar to any specific area or climate, and they can be a common housemate always anywhere. Even though they are one of the most widely spread kinds of spiders, they can be difficult to distinguish.

These insects tend to inhabit spaces in the household that provide them with security and safety. Also, brown recluse control has a set of features to consider for proper detection.

What are brown recluse spiders?

This is a species that mostly dwells in the South of and mid-United States due to their preferences for moisture and heat. Though they may be found in other regions because of an annual migration, they are unlikely to inhibit a less warm climate. Interestingly, only 1 out of 500 spiders claimed by people is a recluse spider since they resemble other similar species.

To identify this kind, there are a few markers to consider. First, a recluse is no bigger than a regular coin with elongated, thin legs and a violin-like body. Second, the largest it can grow up to is 0.80 of an inch, except for the female, which can reach up to 1 inch in length. The typical hair-coat for this one is brown or dark gray colors.

The back pattern is not a highlight for them and it may vary or be completely absent. If you want to distinguish this spider, look at the candidate’s eyes. They are known for their three rows of eye pairs, located with a little curve in the middle of the head.

Moreover, their lifespan ranges from 1.5 to 2 years, with around 50 eggs to lay each season, which makes them one of the most long-living spider species.

What attracts brown recluse spiders?

I’ve been wondering for a long time, why do I keep finding brown recluse spiders in my house? Apparently, there are two common grounds due to which these spiders can find a house or land lot alluring to settle on. As it derives from their name, the pests are extremely into solitude.

They don’t like places crowded with other insects and animals and tend to live alone until it’s time to mate. This way, the spiders find a cozy shelter to make a nest. They prefer dark, light-deprived places filled with dampness and coolness, such as cupboards, kitchen, and living room furniture, or under the sink area.

Another thing that can attract the pests is tall vegetation. There, they feel most secure, which makes up a perfect habitat as they are ready to nest, mate, and breed. Surprisingly, these insects love noise and clamor, most likely because it keeps them alert. Thus, encouraging them to live as close to humans as possible.

Brown recluse spiders dangers

Despite the common belief that this critter is extremely poisonous and can cause a variety of unfortunate outcomes, it’s rather harmless. It’s estimated that a recluse attacks only 1 out of 20 times.

Moreover, they are less agitated than other venomous 8-legged insects and rarely charge you without a good reason. Their behavior is shy and secluded that makes them more of housemates than an occupant.

However, they do bite. At first, the bite is unnoticeable and begins to manifest in a couple of hours. The bitten area swells and reddens, becoming more and more painful. Brown recluse spider toxicity is high, and the wound might result in a scar. Also, it can lead to a blood pressure increase, vertigo, or even a fever.

Signs of a brown recluse infestation

It’s hard to tell if you have an infestation until you need full-blown brown recluse extermination on the property. The spiders are quite sly, and encountering them without looking for them is unlikely. But, two things can make you alert about the pests.

  • Large-scale web contamination. If you notice that webs happen to appear all over the place and their number is constantly increasing, then there can be an infestation. The webs don’t necessarily have to be hidden in a shabby old cupboard but may extend throughout the house.
  • Fly population decreases. Living in warmer areas comes with swarms of flies. In case you’ve detected a sudden decrease in their number or even complete disappearance, it can be caused by this kind. Although it might seem to be great to be freed from flies’ buzzing and disturbance, it also signals that there is a bigger fish to fry.

How to get rid of brown recluse spiders?

Brown Recluse Spider

Upon facing an infestation, don’t worry too much because there are proven ways to exterminate brown recluse spiders. Here’s a little guide!

Step 1: Inspect and clean your house

Start by looking around the residence to find where the nests can be. Pay special attention to isolated, dark places, like the attic, basement, the back of furniture, etc. They find them as the most favorable habitat due to the conditions.

To help you conduct a more thorough examination of the house, make sure to accompany your checks with cleaning. Get rid of the old junk that has piled up throughout the years, especially if it includes old sofas, a chest of drawers, closets, etc. Wash the surfaces, vacuum clean the carpets, and areas behind large comforts as a means of brown recluse spider prevention.

Step 2: Eliminate a food source

Since the insects aren’t always able to catch prey, they might drop in by food closets, bread baskets, or even fridges in search of additional nutrition. Look behind the furniture to see if there is some leftover lying around that spiders find especially delicious.

The same applies to the webs, where spiders catch their prey. Use a brush to disrupt them or apply a vacuum cleaner to suck in the webs, thus taking away their main nutrition. It can be especially helpful in old barns and premises, where spiders have already created a large coverage area for hunting.

Step 3: Seal your house

For complete brown recluse home treatment, it’s essential to block crevices and holes in the ground and furniture. Use a cloth or a sealant to mend the deficiencies near the baseboards, thresholds, and windows. Also, make sure to clean them first before sealing off.

Step 4: Get rid of brown recluse spiders

When your dwelling is secure of further infestation, it’s time to apply treatments for getting rid of brown recluse spiders once and for all. Here, you have a great variety to choose from. But mind that some of them can be more or less effective, depending on the stage of your infestation.


Spider traps are very convenient to use when you have detected that a spider nest is located in a hard-to-reach area. They are extremely safe for people and pets and demand little maintenance. Place them near where a nest is or scatter them around the house. Spiders are lured to them and get stuck until they perish.


Probably, the best way to get rid of brown recluse spiders is to use an insecticide spray. It’s easily applicable to different surfaces and causes little to no damage to fabrics or wood. Spider sprays tend not only to kill the pests but also to prevent them from breeding. You may also use spider foggers as an alternative way of spreading the insecticide.


Using anti-insect dust can be great for brown recluse spiders since they prefer small, secluded crevices and cracks. Spread some of it in and around the area for complete brown recluse removal by desiccation.


You can also apply a natural brown recluse spider repellent like peppermint, vinegar, coconut extract, etc. These alternative pesticides work great when it comes to deterring spiders since the smell is rather repulsive, making the insects flee.
