Spider Control & Extermination

What types of spiders in Mississippi are venemous?  The two most well known and most likely to send nervous homeowners to the internet searching for “pest control near me” are the Black Widow and Brown Recluse.  What about the Wolf Spider(frequently misidentified as a Brown Recluse)?  Spider control in Mississippi can be difficult due to our warm climate.  Favorable conditions for insects mean you can expect tons of spiders to be close by!

Black Widow

The Black Widow spider is easily identified as the female black widow is shiny and black with a red hourglass mark on her underside.  Black widows typically live outdoors but may take shelter in old abandoned houses and buildings.  Black widow spiders are most active during the Spring when a single female can lay between 250 and 300 eggs.  Females typically die by the end of the summer.  

Black widow bites are rare due to they fact that they have difficulty breaking the skin of humans.  It is not uncommon for these bites to go unnoticed as there may not be a lot of pain associated with the bite.  Within an hour of a Black Widow bite you may notice a whie area around the puncture site with two puncture points.  The venom of a Black Widow is considered to be a neurotoxin.  Common symptoms following a Black Widow bite include cramping of muscles, injection site pain, and difficulty speaking.

Black widow spider control is difficult since they spend the majority of their lives outdoors.  Areas around your home where you may encounter a black widow include garages, water meters, and storage buildings.  The best insecticides for spiders outdoors are synthetic pyrethroids in liquid and dust formulations.

Brown Recluse

While Brown Recluse spiders are quite common in Mississippi, human interactions with Brown Recluse spiders are quite rare.  As per their name, Brown Recluses prefer to live reclusive lifestyles in dark areas that do not see much activity or disturbances.  Brown Recluses live the majority of their lives indoors in boxes, behind wall plates, under beds & furniture, and in attics.  

Identification of Brown Recluse spiders is not very difficult.  All Brown Recluse spiders have the unique identifying characteristic of only 6 eyes; whereas, most spiders have 8 eyes.  Also, you may notice a dark fiddle pattern on their backs.  Brown Reclusve bites, like the bites of Black Widow spiders, may not initially be very painful.  Brown Recluse bites can be quite serious though, as bite victims may experience tissue necrosis/death in the area around the bite.

While insecticides may be effective against Brown Recluses, the majority of homeowner efforts should be focused around de-cluttering and removal of empty boxes, etc.  The fewer places there are for a Brown Recluse to hide in your home, the less likely a homeowner is to ever encounter one.

Wolf Spider

Wolf Spiders are commonly mistaken for Brown Recluse spiders.  Unlike the Brown Recluse, Wolf Spiders prefer to live the majority of their lives outdoors, under leaves and in burrows.  Wolf Spiders are venemous and do bite; however, they rarely bite humans.  Insecticide sprays an dusts around the exterior of a building or home may help prevent Wolf Spiders from coming indoors.  If you do identify a Wolf Spider in your home, the best way to prevent additional Wolf Spiders from coming in are to seal and repair all windows, doors, and cracks.

Frequently Asked Questions About Spiders, Spider Bites, and Spider Control

1.What kills spiders instantly?   

Instant control of spiders can be difficult.  While most insecticides in liquid, granular and dust formulations are effective against spiders, it may take time as the insecticide usually needs to contact the spider’s body to be effective.  

2.What is the best insecticide for spiders outdoors?

Any of the synthetic pyethroid insecticides will be effective against spider infestations.  A good tip for outdoor application of these insecticides is to first spend time remove all webbing to prevent re-infestation.

3.How do I get rid of spiders in my house?

A combination of the following methods may be useful:

-Application of a liquid insecticide

-Use of glue boards to trap spiders

-Remove clutter and empty boxes

-Seal all exterior doors and windows

4.What to do if you suspect you have been bitten by a spider?

Seek medical attention to confirm whether the affected area is really a spider bite.  Common skin infections caused by Staphylococcus Aurea are frequently misidentified as spider bites.

5.How do I prevent spider webs around my house and under the eaves?  Spiders love to live and build webs in areas of high insect activity.  Houses closes to lakes and houses with lots of exterior lighting are very attractive to insects, and thus, spiders.  Frequent de-webbing around your home may help with spider control.  Swapping exterior light bulbs for “yellow”bulbs that are less attractive to insects may also help reduce the number of spiders and insects around your home.
