In the wild, brown recluse spiders have a number of natural predators, including:
Diatomaceous Earth is actually a food-grade product that some people take as a supplement...so it is obviously entirely safe to use in your home!

Their web is a sheet web that is small and loose and shapeless. Birds, insects, and other spiders are predators on the brown recluse.
Wolf spiders will hunt and eat brown recluse spiders (also known as fiddlebacks), in addition to venomous black widow spiders, cockroaches, crickets, beetles and silverfish.

Brazilian wandering spiders
It has a highly toxic venom and is regarded (along with the Australian funnel-web spiders) as among the most dangerous spiders in the world. Based on one of the few pharmacological studies performed in the 1970s, Phoneutria's venom toxicity was more virulent than both Atrax and Latrodectus.
Wolf spiders are large, agile hunters found worldwide, with over 2,300 species known for their excellent vision and lack of webs. These spiders are harmless to humans and beneficial as they help control pest insect populations in homes and gardens.
The brown recluse is smaller and has six eyes. The wolf spider has eight eyes and is considerably larger. One of the key differences between brown recluses and wolf spiders is the brown recluse's violin-shaped mark on its back. Wolf spiders do not have this marking, making them easy to distinguish from brown recluses.
Wolf spiders are not aggressive and will not bite unless frightened or provoked. Although their bite is not deadly, it can be very painful. Wolf spiders typically only bite humans if they are handled or touched. They usually avoid humans and run away when people are nearby.
Brown recluse spiders are attracted by food, water, and shelter. They eat insects and other spiders, so if you have a lot of pest activity on your property or in your house, they'll have reason to hang around.
More than 80 percent of brown recluse spiders are found throughout the south-central and midwestern United States. They're most common in Southern California (just like a desert recluse), Texas, Florida, Kentucky, Ohio, Kansas, and Alabama.
Because this species of spider is so dangerous, we do not recommend trying to kill brown recluse spiders naturally. To kill brown recluses, we suggest using a residual insecticide as a perimeter spray such as Onslaught Fastcap, Suspend Poly Zone, Demand CS, Avesta CS, and Cyper WSP.
Spiders in general are not fans of strong smells, brown recluses are no exception. Potted indoor eucalyptus played on windowsills can be a strong deterrent to spiders.
The brown recluse, L. reclusa, in its normal range, prefers to inhabit gaps under rocks, boards, and the bark of dead trees and logs. In structures, it will live inside cracks in walls and boards and behind and under any number of items in storage. The brown recluse prefers nesting sites that are warm and dry.
One of these bad decisions is trying to physically hit or squish a brown recluse. Doing so puts you in close proximity to the spider and makes it feel threatened. This is a combination that significantly increases your chances of getting bit.
Killing any living organism is not good, no matter how scared you are of it. Specifically speaking of wolf spiders who are carrying babies should not be killed. Squishing a pregnant wolf spider could be pretty dangerous and nasty.
WOODLOUSE SPIDER (Dysdera crocata)
This spider is sometimes mistaken for the brown recluse spider, though there is only a vague resemblance between the two. Yet, like the brown recluse, the woodlouse spider has six eyes and is most active at night. This spider has a ½-inch long body.
If you squish a wolf spider that's carrying her young, you may inadvertently send dozens of her babies into different cracks and crevices of your home. Counterintuitively, this may create more of a spider infestation in your home than if you had left it alone.
Inside the house, they eat pests like flies, roaches, mosquitoes and more. Because they eat disease-carrying insects like mosquitoes and flies, they help control the spread of diseases that cause problems for humans. Their venom is used in medicines. Their silk was used as a model for creation of synthetic silks.
Along with boric acid, other natural repellents safely keep wolf spiders away. Many essential oils and natural herbs keep spiders away. They don't like the cedar, cinnamon, citrus, peppermint, and tea tree fragrances. Fill a BPA-free bottle with peppermint oil to repel spiders, ants, and other bugs.
Yes, being sucked up by a vacuum can kill spiders. The dramatic change in air pressure and the powerful force of the suction can be fatal for the spider. Plus, the sudden impact and the lack of air flow can also cause significant trauma to the spider's body, leading to its death.
Selecting the Right Pet Spider for You
The best beginner spider would be a tarantula such as the Chilean rose, Mexican Redleg, or Costa Rican Zebra. These species aren't terribly venomous and are pretty docile when compared with some other tarantulas (their venom is comparable to bee venom).
The blue-ringed octopodes (Hapalochlaena spp.) produce tetrodotoxin, which is extremely toxic to even the healthiest adult humans, though the number of actual fatalities they have caused is far lower than the number caused by spiders and snakes, with which human contact is more common.
The two most venomous spiders that pose potential risks to humans in North America are black widows and brown recluses. The Centers for Disease Control and Prevention (CDC) specifically highlights these species due to how dangerous their venom is.
