Best Spider Killer Reviews 2021

#1.  The 363 Spider and Ground Bee Killer

It also works on many other insects including ants, crickets, earwigs, millipedes, cockroaches, sow bug (pill bug), silverfish, clover mites, wasps, and hornets.

The formula is in the dust form and contains permethrin .25% as an active ingredient. Regular usage guarantees reduced painful stings and bites during gardenwork and around the house. It is a good, budget solution for recurring spider problems, for people living with gardens, yards, around trees.

The repellant is in a dust form and caution has to be taken when using it on breezy days, or near air vents, fans, etc. It is meant for light use, just on a few insects and not really a nest of hornets. The applicator is narrow, and this might not give you the best reach. It can even get clogged easily with the dust and has to be cleaned out for use.

It does target all insects in areas its been applied too, so be careful about this. Also, the powder is difficult to apply on wet yards and can be washed away easily by watering the lawns or by rains rendering it ineffective.


  • Convenient 10 oz.puffer applicator size works on many other insects.
  • Snorkel tube applicator for hard to reach areas.
  • Indoor/outdoor use.


  • Narrow applicator.
  • Dust tends to spread with the breeze.
  • Light usage.
  • Can’t be used in rains or wet soil.

#2. Revenge Spider Killer Indoor and Outdoor Spider Control

But, Miss Muffet’s Revenge Spider Control might be good enough for detection, not prevention. This might not be strong for areas that have regular spider visits. It kills on contact and that’s it, working more like an insecticide and less like a control measure, only more expensive.

Next, the applicator bottle is clumsy to use – you have to snap the nozzle’s tubing into the bottle cap, instead of the conventional spray nozzle that you screw on. Spraying at a higher place, results in a shower of insecticide.


  • Comes with jet and spray nozzle applicator bottle,
  • Ready to use mix in a separate gallon bottle,
  • Easily reach higher up areas,indoor/outdoor use,
  • Effective up to 12 months.


  • Not good for recurring spider webs.
