Insecticides For Brown Recluse & Where To Buy

The brown recluse spider is a small, secretive arachnid who, over the past 40 or so years has made its home in the American South and Midwest. In some areas, this out-of-towner has come to be regarded as one of the most poisonous spiders, though under the right circumstances, it is actually very difficult to kill — unless you pour enough insecticide on it.

The most important thing you can do to prevent these venomous spiders from establishing a foothold in your home is to use caulk to seal cracks and crevices through which brown recluses can enter. Pay special attention to areas around windows, doors, vents, and utility pipes, as these are the most likely places for cracks to develop.

It’s also a good idea to move woodpiles and yard debris away from the side of your home, as this spider prefers to make its home in such shelters. Similarly, cut tall grass and clear any climbing ivy off the exterior walls of your house. Since brown recluses use other insects as a food source, keeping up with general pest control in and around your house is also important.

Signs of Brown Recluse Infestation

If you suspect Brown Recluse infestation, take a look at your home’s exterior. Brown Recluses are commonly found in basements, attics, crawl spaces, and other dark places where they can hide during the day. They often build their webs in corners of rooms or under furniture.

You may also notice damage to your property. Brown Recluses are known to feed on many different kinds of materials including wood, cardboard, and clothing. If you notice holes in your walls or floors that seem out of place, it may be an indication that a Brown Recluse has been feeding on these areas.

You may also see signs of an infestation if you find small white egg sacs near the spiders’ hiding spots or around their webs. These sacs contain up to fifty eggs which hatch into new spiders after about 30 days!

What Causes Brown Recluse Spider Infestation?

The brown recluse spider, or Loxosceles reclusa, is a poisonous spider that can be found throughout the United States. It’s also known as the violin spider because of the characteristic fiddle-shaped marking on its back.

Brown recluse spiders are nocturnal creatures that lay their eggs in late summer and early fall. They prefer dark corners and crevices where they can spin their webs without being disturbed. When they build their webs, they create irregularly shaped strands with sticky ends so they can trap insects to eat.

The most common areas for brown recluse infestation are basements, garages, closets, and attics where there are plenty of dark places for them to hide out during the day. They also like humid areas such as bathrooms or laundry rooms where moisture is present from leaking pipes or running shower heads.

If you see one or more brown recluse spiders in your home, you should take steps immediately to eradicate them before they start reproducing in large numbers and become an even bigger problem for your household!

How Do You Protect Against Brown Recluse Spiders?

Brown recluse spiders are a serious concern for many homeowners. They are known to bite people and cause skin infections, and they are difficult to get rid of. Brown recluse spiders can be found in almost any area where there is wood or dead leaves on the ground. These areas include attics, basements, garages, under decks and porches, in woodpiles, and lawns.

The best way to prevent brown recluse spiders from entering your home is to seal up any cracks or holes that could allow them access. You should also make sure you do not leave out any food that could attract them. Finally, make sure all shoes are removed before entering your house so as not to bring any outside insects inside with you.

How to Get Rid of a Brown Recluse Infestation

Again, we strongly recommend professional pest control, but if you have reason to believe the infestation is small and you want to try a DIY approach, here are some steps you can take. Remember that before starting any kind of inspection or treatment, put on long sleeves, gardening gloves, and boots to protect vulnerable skin. Brown recluse fangs are small and can’t pierce clothing.

Natural Remedies

Begin with the prevention methods listed above, then dust and vacuum your home thoroughly. You can lay down sticky traps in areas where brown recluses generally hide, including attics, basements, closets, and garages. There is any number of “natural” products that claim to repel spiders with essential oils or strong scents. However, remember that repelling spiders don’t kill them.

Home Remedies

You can make a solution out of apple cider vinegar and water and spray it on any brown recluses you see. However, there’s no consensus on whether this works, and vinegar is usually suggested as a cure-all in terms of home remedies for all cleaning and pest problems. Diatomaceous earth sprinkled on a surface will kill brown recluses, but it works slowly, and the spiders have to come into direct contact to be affected.


The most reliable way to kill brown recluse spiders is with an insecticide. If there’s an infestation, some brown recluses will always be able to avoid sticky spider traps and diatomaceous earth, particularly egg-laying females. For your safety and that of your family, the benefits of using synthetic pesticides outweigh the risk as long as you use them as directed by the manufacturer.

Fortunately, many broad-spectrum pesticides like cyfluthrin, bifenthrin, deltamethrin, and lambda-cyhalothrin are also effective against brown recluse spiders. These are available in spray, liquid, and dust forms. All of these are best used in targeted areas, that is, sprayed or blown into cracks and crevices where brown recluses are likely to be hiding. Whole-house foggers are rarely effective.

Follow the directions on the insecticide packaging and keep it away from children and pets. Once again, it’s a good idea to start with prevention methods to seal your home and glue traps to determine where to start treatment.

When to Call in the Pros

With brown recluses, it’s a good idea to head straight to the pros from the start. However, if you’ve tried to treat the problem yourself to no avail, it’s definitely time to consult a pest control company. Although serious complications from brown recluse bites happen only about 10% of the time and are rarely fatal, these complications can be very painful and cause deep scarring. It’s entirely worth the money to have experts handle brown recluse infestations.

In Conclusion,

Insecticides for brown recluse spiders can be effective when used properly, but they are not a cure-all. It is important to understand that these insecticides are only effective when applied directly to the spider or its nest, which can be difficult to find. They will not prevent bites or stop the spread of infection from one person to another.

Insecticides for brown recluse spiders are also not a good choice if you have pets in your home. While these insecticides can be fatal to brown recluses, they are also harmful to cats, dogs, and other animals with fur. Consequently, it is important that you keep your pets away from areas where you have sprayed insecticide for brown recluses.
