Joro Spiders are an invasive species not native to the southeast but none the less, quite comfortable living here. First discovered back in 2013, they are large, 3 inches or more, and very similar looking to another common spider known as the “banana” or “spider writer” Argiope.
Like most web makers, the Joro spider is venomous but in general, their bite won’t be lethal unless you are allergic to their venom.
They do create large webs and in the yard, can be annoying and threat to pets and kids who unknowingly get entangled in their web which typically forms from 1 foot to 6 feet about the ground.
Once in the yard, the Joro spiders will thrive assuming you have adequate food and their reproduction cycle will allow them to produce hundreds of offspring annually. For this reason activity tends to get “worse” once they’re around, especially so if you have a lot of shrubs and ground cover.
Treatment for the Joro is easy using our MAXXTHOR in a HOSE END SPRAYER.
Simply add 2.5 oz of Maxxthor so the sprayer and some water so its filled up to the 5 gallon line. Attach the sprayer to the hose and use the mixture to cover up to 5,000 of yard which is about 1/8th of an acre.
Be sure to spray the sides of the home as well, right up to the first soffit or overhang at least, since they will readily nest on structures and from there, can get into homes.
Our 20 gallon hose end is ideal for applying this product around the yard since it uses the power of your garden hose to deliver the mixture. This is important since getting the right coverage can only happen if you use enough water.
Spraying the outside yard and sides of the home should keep them from getting inside but if they do invade, use FS MP AEROSOL around windows, doors and other points of entry to kill and keep them out. FS MP works fast. It has a slight odor but its strong to handle this spider and works fast on them given their large size which prevents many common sprays from doing the job.

I live in Virginia, and as I have arachnophobia, I am terrified that these spiders will come here. I would like to ask if the spray you have for sale is washed away by rain if it is used in the yard or on the sides of the house. Does it have to be reapplied after each rain?
Tech Support says
In general, pesticides work like cement. When you get a bag of powdered cement, you add water to make a slurry. Once you place out the slurry and the water dries, the cement remains in place and won’t go back into solution. Pesticides are the very similar. So to start, you can mix it once and that will be for the application. But assuming it has time to dry following the application, the treatment will “adhere” and stick to where you sprayed it. And once in place, treatments will provide a solid month of protection.
With that being said, treating around the home and yard – plants included – would be a great way to insure they don’t move in.
