My Story Behind This Spider Spray

About a month ago, I decided to create my own DIY spider spray, and I was amazed by the results. Let me share my journey with you. We were dealing with a spider infestation in our garage – there were spider eggs in one corner, and tiny spiders were appearing all over their webs. It was quite unsettling! So, my husband and I headed to our local Dollar General in search of a spider killer/repellent.

To my disappointment, I couldn’t find any spray that was nontoxic, safe for indoor use, and effective. Feeling frustrated, we returned home, and that’s when I started my research. Many people suggested using peppermint essential oil, but I wasn’t convinced. As I continued my search, I stumbled upon a study about spiders and cinnamon essential oil. Intrigued, I searched for a nontoxic spray recipe using cinnamon, but to my surprise, there wasn’t any I liked, so I decided to create my own.

After making the spray, I hurried downstairs to the garage and started spraying away. To our relief, it not only repelled other bugs but also killed the spiders and the babies hatching from the eggs! I must admit, my situation was pretty bad, and I ended up using a full 16oz spray bottle to completely deal with it – but don’t worry, you probably won’t have such a severe issue haha.

Why This Homemade Spider Spray

  • Every ingredient has a purpose
  • This spray can be used indoors or outdoors
  • Not only repels but can kill spiders (spray liberally to do so)
  • Frugal way to deal with spiders
  • Used by yours truly, so it won’t waste your time or money

Important Information To Note

This sider spray is nontoxic but still use caution around children and pets due to the cinnamon essential oil (which can be harmful to them if not diluted or used properly). Just keep the spray out of their reach, use it when they’re not around, and exercise caution or contact a medical professional/veterinarian for help.

Does this Spray Actually Kill Spiders

In my experience, this DIY spider spray has been fantastic! As I shared in the story behind it, I used the spray to eliminate two large spiders and two egg sacks that were full of baby spiders hatching. The powerful blend of vinegar and cinnamon essential oil worked wonders, as the soap in the mixture helped the solution adhere to the spiders’ bodies, effectively taking care of the problem.

Not only did it get rid of our spider infestation entirely, but I also now use it to repel spiders all around our home. It’s essential to note that while it may require more spray to kill a spider than to repel them, the results have been well worth it.

The combination of vinegar and cinnamon essential oil has proven to be a winning solution, and I couldn’t be happier with the outcome. Say goodbye to spiders with this DIY spray – it truly works wonders!

Spider Spray FAQ

  • Is this spray safe around kids and dogs? This sider spray is nontoxic but still use caution around children and pets due to the cinnamon essential oil (which can be harmful to them if not diluted or used properly). Just keep the spray out of their reach, use it when they’re not around, and exercise caution or contact a medical professional/veterinarian for help.
  • What is the best castile soap for this DIY? I love the Whole Naturals brand from Amazon (or their website)
  • How long does a bottle of this spray last? If you’re using it to repel (not kill) it should last 1-2 months.
  • What kills spiders in this spray? The mixture of cinnamon and vinegar being held on by soap kills them.
  • Can I use a plastic spray bottle? No, the essential oils will weaken the plastic.
  • Can I use other essential oils in this spray? I wouldn’t due to it already working so well.
  • I don’t like the smell of cinnamon, how long does the scent last to a human? Depending on how much you spray it could be anywhere from 15 minutes to 1 day (this would be if it was in an enclosed garage and you use the entire bottle).
  • My spray has separated why did this happen? This is normal due to natural ingredients, just shake it before using each time.
