Where does the brown widow spider live?

Brown widow spiders, are found in warm and dry areas like California, Florida, and Texas. These spiders are usually not aggressive but may bite if they feel threatened or cornered.

What does a brown widow spider look like?

These spiders can be almost black or brown in color. Their bodies are about an inch long, including their legs, and they have a shiny appearance. They are not aggressive but may bite if they feel threatened or cornered due to their nervousness. These spiders resemble black widows. The best way to tell them apart is by how big the males’ hourglass marking on their abdomens are compared to the females’. Another identifier for this spider is by how many white markings there are on its back. 

Is the brown widow poisonous?

Brown widow spiders are not poisonous, and their bite is usually harmless to humans. However, it can be quite uncomfortable for people who have sensitive skin.

Their bites may cause mild symptoms that typically go away on their own within hours of the incident taking place. These spiders do not produce a potent venom like other species of spiders that would require antivenom treatment. Still, they will bite if scared or startled, resulting in a painful experience for people handling these arachnids.

They enjoy hunting insects and are often found outside in gardens where they use silk to create webs so they can ambush prey coming close by them. Brown widow spider bites should only be considered an emergency if allergic reactions or any medical conditions present that might increase susceptibility to spider venom.

These bites are usually only treated with over-the-counter medications and creams to relieve pain and other symptoms. In contrast, the bite heals on its own without medical intervention or hospitalization.

How do I stop brown widow spiders from entering my home?

Brown widow spiders are commonly drawn to the warmth of the indoors, so it is important to make your home less appealing to them. Spider webs and crumpled papers or other debris that form dark crevices around windows, doors, furniture, or whatever they can find in a home provide an ideal climate for these unwelcome visitors. To reduce how likely you are attracting these arachnids into your house, continue the following steps:

  • Keep clean and vacuum regularly.  If you see any signs of spider activity in your home, be sure to clean up this mess and vacuum anywhere there are webs. Ensure to empty the canister or bag as soon as you are done vacuuming so that spiders do not have a place to hide!
  • Wash all clothing and bedding before storing them away in dressers or closets. This will ensure nothing can set up camp near your bed where they might find it easier to startle you when you least expect it.
  • Make sure exterior doors have tight-fitting screens on them. If these spiders manage to make their way into your house, they will appreciate how difficult it will become for them if they cannot exit through windows without having something in the way.
  • Use bug spray that has Pyrethrins in it. These are plant-derived compounds that work to kill off insects and spiders on contact. Spray this product around doorways, along windowsills, and any other areas you see spider webs infrequently.
  • Wear long pants and shoes when outdoors. This will help protect your skin from these spiders if they are around and not something you want to run into. Even though brown widow spiders do not usually bite people, it is best to be safe than sorry when handling these arachnids!
  • Remove or replace leaf litter from the edges of a garden area. This can provide shelter for spider eggs, often laid in sacs made of silk hidden underneath leaves. Washing away debris where there may be piles of leaf litter or trash increases how safe it is to work outdoors without fear of running into them.
  • Use a vacuum cleaner to remove webs under furniture and inside cabinets. This will ensure nothing has the chance to make its way into spaces that can infest them with how many spiders might be living inside.
  • Seal cracks in your foundation where they could enter.  Keep an eye out for how much space there might be between your house and ground or how large gaps could exist at the place where pipes enter into your foundation.
  • Use sticky traps around entry points. These spiders are commonly found along with window sills where how heavy traffic of people entering and exiting a home can create opportunities for them to travel inside.
  • Seal windows and doors with caulking or weatherstripping. This is how to keep them how they cannot leave or enter your home! This will also help prevent how much cold air pours inside your house during the spring and summer months.

How do I get rid of brown widows in my home?

Here are some quick tips on how to get rid of brown widow spiders and how they can be a threat in your home.

Insecticides and pesticides

When getting rid of brown widow spiders in your home, you will want to try insecticides and pesticides. You can purchase these chemicals at a hardware store or garden center. One of the most popular options is D-Limonene Extract – it’s plant-based and has no odor, which means you won’t be getting a chemical fog throughout your house. You will want to use this solution once or twice a week for about three weeks. This will kill all the brown widows inside your home and prevent any more from coming back in!

Add birds and plants as deterrents

It is good practice to add plants and birds to your home as both animals are natural predators of spiders. Without these natural deterrents, the brown widow spiders will be able to move into your home unimpeded.

Also, a warm, arid climate and dark, undisturbed corners in which the spider builds its web provide an ideal breeding ground for these creatures. In essence, brown widows need a food source (bugs), moist areas that suit their egg-laying activity, shelter from predators (and man) during molting or mating periods.

These pests can reach lengths exceeding 1/2 inch in size, with some possessing yellow or orange abdomens instead of black markings on top and below; in other words – distinctive identifying characteristics that differ from those of the black widow. In some instances, brown spiders may live inside old appliances or other discarded items outside a home where they can be activated and triggered to move without your knowledge.

Strong scents

Strong scents are a key part of getting rid of brown widows. They provide natural spider predators that will come up and eat the spiders in your house, which is one way to help keep them away. If something has a strong smell, so will the brown widows.

The very unpleasant odor is used by some spiders as well as some insects in defense. This chemical is easily acquired through plants or even certain fruits like citrus peels and peppermint extracts; it’s only natural that somebody would want to avoid these smells due to its potent ability for repelling unwanted guests or pests!

Entering your home undetected through electric sockets, box drains, water heater tanks, pipe cracks, and crevices to lay its eggs. Homeowners and residents should check the interior of their homes for the presence of this spider as it can cause harm to humans in large groups.


Vacuuming is one of the best ways to remove brown widows from your home. Vacuuming removes eggs these spiders will have laid during their molting and hiding periods throughout your home, keeping you and future generations safe from another infestation.

Homeowners should take time to vacuum every corner inside their house at least once a month while emptying the bag or canister frequently; this way, it is easier for residents to get rid of brown widows with minimal exertion on their part!


Vinegar contains acetic acid, which can be used to get rid of brown widow spiders. Vinegar is an all-purpose household cleaner that will kill the eggs of brown widows.

  • Step 1 – Make sure the areas where you plan on treating brown widow spiders are thoroughly dry because vinegar will not work if the area is wet.
  • Step 2  – Apply a generous amount of vinegar as an insecticide on several separate joints in your home, such as door thresholds, window sills, and around corners in rooms with furniture next to walls; reapply after a few hours or at night if necessary for better coverage. It may take up to four or more applications before most brown widow spider infestations are eradicated from your house, so use it sparingly and not all at once!
  • Step 3 – Allow the area to dry. Even though acetic acid is natural, the smell can be unpleasant to some people. Try to open up windows or make sure whatever area you are treating has a good ventilation system throughout the house, so the smell does not linger.
  • Step 4  – Since brown widow spiders are nocturnal, be sure to sprinkle ground pepper where you have applied vinegar to help keep brown widow spiders away.

Insect traps

Insect traps keep the spiders from having a food source from bugs which can help you manage how many are in your home.

Brown widow spiders, usually survive on other smaller insects, and these insect traps that specialize in capturing and trapping small bugs are how they work to ensure the brown widows around your home are cut off from their food sources.

It would be best if you replaced the traps every month to maintain the effectiveness and features of controlling brown widows without the hassles of crawling out of the way to get them. They are very inexpensive, but it is not as easy as just replacing an ordinary product because brown widow spiders gather near power sources, such as outlets, lamp cords, even phone chargers! It takes time before all critters have been removed from your home.

Flash freezing

If you want to get humanely rid of the spiders, then flash freezing them is how you go about it.

Freezing is how you get rid of brown widow spiders through flash freezing, which involves placing the spider in a closed glass container with an ice pack. Flash freezing the spiders in this way does not damage them, and they can be released back into their natural habitat if desired; therefore, it is how you get rid of brown widow spiders most humanely and respectfully possible!


If you want to get rid of brown widow spiders in your home, check the interior for their presence and how they may have entered. Once that is done, try some simple steps such as vacuuming or using vinegar to remove them from hiding.

You should also replace insect traps every month because these spiders like hanging out near power sources around your house! If all else fails and you need help with getting rid of brown widow spiders humanely, then flash freezing might be a good way to go. The most important thing is making sure this spider does not become a problem again, so make sure you vacuum frequently and watch how many insects there are inside your house!
