Unlike others on the list, this one comes with a bottle of pesticide concentrate, a battery-powered applicator spray wand, a mixing and application bag, a pair of gloves, and an instructional guide to help you manage pest control yourself.

It has two main ingredients, pyrethrin, and deltamethrin, to kill various species of spiders like a black widows, brown recluses, and hobo spiders, whose bites can be deadly.

Similar to Superior DIY Pest Control, the Terro T2302-6 is safe to use around children and pets. However, it’s specifically designed only to kill spiders and similar insects, so you’re very limited when dealing with other pests, and you might need to buy additional products. It kills spiders on contact, making it an excellent option for eliminating Joro spiders quickly. Unlike Control Freaks, which comes with a mix and application bag, Terro T2302-6 only requires you to turn the dial at the top of the can and press it to spray.

Like Superior DIY Pest Control, which is safe and easy to use, this one also comes with a spray bottle and nozzle for easy application. It can be used indoors or outdoors, making it a great solution for those who want to eliminate Joro spiders without harming the environment.

Unlike Control Freaks Unite, which lasts six weeks after initial application, Wondercide’s protection lasts only four weeks, after which you will need to reapply the spray. Unfortunately it does not have a long-lasting effect, so you may need to re-apply the spray more often.
