A DIY Organic Garden Insect Spray That Works!

2 Materials
10 Minutes

I have had problems in my backyard herb garden for a couple of years with some type of insect that devoured basil and marigolds (often the least-touched plants). I had tried a couple other organic pest deterrents with limited success. But this year the bugs were particularly bad and made their way across the path to eat all the growing tips of a trumpet vine.

If I was going to get enough basil for our year's worth of pesto and a bloom on the trumpet vine, I needed to take action.

One of the things I had tried briefly last year that seemed to work was a homemade garden insect spray made with garlic and mint, a bit of cayenne and soap. So I decided this year to write down a "recipe" and record the before-and-after pictures to share the results. And I'm glad I did - I was blown away by the success of this easy, natural pest deterrent!

This shows how bad the basil had been attacked by the mystery bug (some have suggested earwigs, but I've never seen them), 2 weeks after spraying and then 4 weeks later. Can you believe it?

This is a super healthy basil plant now - even more healthy than my main garden basil that wasn't ever attacked. Seriously amazing.

Here's another before and after for you: the bugs attacked most of the tender new growth of my trumpet vine.

After only 2 sprayings (and a bout of rain after the 1st), the trumpet vine is loaded with new growth and I'm having to prune it back (if you know anything about trumpet vines, you'll know it's back to normal now, ha!).

    Just be careful- last year I repeatedly sprayed my porch & garden with peppermint oil & water and had no bugs- it was great until I noticed some veggies were not growing because the pollinators would not come near the garden. This year I’m planting marigolds in my garden & daily checking the garden for bad bugs. I also sprayed the oil in my car because mice were sneaking in & it works.

    Very frustrated. I gave you my email and went through all your hoops just to get this recipe and cant' find it. If you really like your followers, add the link to the picture above. Badly done.
