Thieve's Oil

I had noticed I was spending more time lately swatting flies away and that their numbers were growing. I have to keep both front & back doors open for airflow as not to run the a/c all day, but could not figure out how to get rid of them. After reading up for an hour or two of research, I came up with a winning recipe:

  • 1 large spray bottle
  • 1 bottle of Remede de Marseilles (aka Thieves Oil)
  • Dish soap
  • Glycerine (if you have)
  • 1 bottle of vinegar

I fill up my sprayer with 1/2 water, 1/2 vinegar, 8 drops of Thieves Oil, 8 drops glycerine, 8 drops dish soap. The glycerine helps the solution adhere and the dish soap coats their wings. This spray kills them quickly if you can douse one, but you will find dead ones later too! It also smells amazing and clean in your house!

I also laid down a large layer of diatomaceous earth (DE) with salt over top of it to keep the dust down, and noticed the flies would land on it, a lot, and later found those ones dead. Both dry them out.

2 days now and I went from 35+ flies down to 1 or 2 (and I'll get them too today). It's like my spray bottle is a video game controller and I do battle with flies by spraying alot! I'm pretty good at it too and hey, it's fun. Once I get them to land on a certain window screen, they are toast. I am fast on that sprayer button! This spray also works on other flying pests too. Also gotta recommend the DE & any-kind-of-cheap-salt on the floor! I will keep it down for another day and then clean up. My floor has been a valuable ally in my battle against "the swarm".

Best of health, everybody!
