Spider Spray – Top 3 Most Effective

Although almost all spiders are completely harmless to humans, most people still don’t want to share their homes with creepy crawlers. Instead of smashing these critters with your hand or a napkin, spider spray presents a useful alternative. All of the sprays discussed in this article also work against many different types of insects. You can reuse these sprays if you ever run into issues with ants, fleas, roaches, or other insects. Additionally, these spider sprays effectively kill North America’s deadly “big three” spiders: brown recluses, black widows, and hobo spiders.

Our Rating: 4.7/5

Pros

  • An effective direct-contact killer 
  • Safe for indoor and outdoor use
  • Formulated to be most effective against spiders

Cons

  • Must be relatively close to spray (12 to 15 inches away is recommended)
  • Can only spray in a mist setting

Comments:

Terro’s spider killer aerosol spray is a popular and effective choice as a spider spray. This product uses the active ingredients of Pyrethrins (.05%) and Deltamethrin (.02%), which have been proven as effective against spiders. This product’s intended use is to kill spiders, not to repel them.

Terro’s spider spray is most effective with direct contact. However, you can achieve less reliable results by spraying where spiders are most active in your home. In fact, spider sprays in general work best when sprayed directly on the spider. Spraying an area that spiders will walk over later provides inconsistent results with most sprays.

Pros

  • Made with natural, organic ingredients 
  • Safe to use around pets and children
  • Has both jet and mist spray settings, allowing for choice in the application method
  • Can be used inside and outside

Cons

  • Similar sprays can be made at home using essential oils
  • Only kills by direct contact

Comments:

Instead of being made with ingredients that could potentially be harmful to pets or children, this spider spray relies on natural and organic ingredients. Natural spider sprays rely on the power of essential oils to kill spiders. This spray in particular uses peppermint oil, spearmint oil, and rosemary oil. Although these ingredients are non-toxic for humans, they’re still lethal for the spiders roaming your home.

Pros

  • Powerful and shown to be effective on even the most difficult to kill spiders 
  • Made with proven, well-researched insecticide ingredients 
  • Covers and protects large outdoor areas
  • Can be diluted to your desired concentration

Cons

  • Only for outdoor use
  • Quite a strong chemical odor

Comments:

This insecticide has a scary enough name to combat the scary-looking critters in your home. Although this spray advertises itself to primarily get rid of termites, it can kill over thirty types of insects - including spiders. Demon Max Insecticide should only be used outside, and it has a strong, unpleasant smell. However, the effectiveness of the spray against spiders is unquestionable. 

This product contains an extremely concentrated amount of the active ingredient Cypermethrin. Once an insect comes into contact with Cypermethrin, their nerve cells are affected, which leads to paralysis and death. To use Demon Max Insecticide, you dilute 1.3 to 5.1 ounces of this spray for every gallon of water. We recommend this spray if you have a large outdoor area you want to cover, such as a shed, patio, or the exterior of your home. Demon Max Insecticide is also extremely useful as a crack and crevice or spot treatment.
