Should You Kill Spiders?

Here at Go Repel, we do not like to mislead people. Should you kill spiders in your house?

The short answer to the question is no; you should not kill spiders in your home. That’s because most home spiders are harmless and good for the ecosystem. Although most spiders are poisonous, their venom is too weak to cause serious problems to humans.

However, home spiders like black widow or brown recluse can be dangerous when threatened. As per our recommendation, repelling the spiders is the best solution. Catch the spiders and throw them far from your house.

But if you are scared to catch spiders, you may try to eliminate them. You can use wasp spray on the spiders. But how? Let’s find out.

How will wasp spray kill spiders?

Pyrethrins, Pyrethroids, Deltamethrin, etc. chemicals are quite effective in killing spiders. If you check popular spider spray killers such as Ortho Home Defense Insect Killer for Indoor & Perimeter, it uses Pyrethrins and Deltamethrin as key ingredients.

On the other hand, if you check wasp sprays such as Raid Wasp and Hornet Killer use Prallethrin, Cypermethrin, Pyrethroids, and other chemicals. Comparing both sprays, they are not exactly the same.

So, does wasp spray kill spiders? Although the key ingredients are different, chemicals in wasp sprays are also life-threatening to spiders. Besides, the wasp spray includes some other chemicals which can eliminate almost every insect.

How to use wasp spray to kill spiders?

If you have a spider in front of you, point the wasp directly towards it. Then spray directly on the spider for a few seconds before it crawls away. The spider won’t be able to survive such actions.

When the wasp spray will not kill spiders

Following are some situations that will not kill spiders using wasp spray:

  • Too little spray: If you spray for only one second on the spider or it runs away instantly, the spray will not kill the spider. The spider may feel bad for a while but will be normal soon.
  • Spraying on spider web: Many people spray on the web, thinking when the spider returns, it will be dead. But such actions won’t affect the spider.
  • Spraying all over the house: Only direct spraying with wasp spray can kill the spiders. Spraying around the house won’t prevent spiders from crawling.

Tips to Prevent Spider Infestation

As most house spiders are, we do not recommend you kill them. Instead, we recommend you take the necessary steps to prevent spider infestation in your house.

Here’s how to get rid of spider infestation:

  • Use peppermint oil: Spiders hate the smell of peppermint oil. You can use peppermint oil to repel spiders from your house and prevent infestation. Add a few drops of peppermint oil into a spray bottle and then spray it to areas you have noticed spider activities. If you do not have a spray bottle, you can drop the oil in different places too.
  • Use vinegar solution: Vinegar solution is also a great natural insect repeller. Mix it with water in a 1:1 ratio and spray wherever you see spider infestation. If you directly spray the mixture on the spiders, it may even kill them.
  • Eliminate spider webs: Removing spider webs from your house is another way to prevent spider infestation. You can use a vacuum cleaner to eliminate the webs. Try using BISSELL CleanView Swivel Upright Bagless Vacuum Cleaner. It’s a great product with a lot of positive feedback. Or you can remove the web manually.
  • Set-up spider traps: You also can purchase Non Toxic Spider Traps and set them in your house to prevent spider infestation. These are mainly glued board sheets. Set them in different places of your house and when spiders get stuck on the traps, catch and throw them away from the house.
  • Keep your home clean: When every corner of your house is neat and clean, the chance of spiders becomes less. Try to clean your house well regularly to keep the spiders away.
