HI Saundra, it all depends on the bugs. Neem oil is great for soft bodied pests, like aphids. But BT is great for worms and other "eaters." Here's a link to my natural pest control page. Good luck! https://thekitchengarten.com/in-the-garden/natural-pest-control/

Dollar store Listerine but only the Gild color Original formula. It works on people too. I get eaten alive outside no matter what method I have tried. Put not when using that. I just used an empty spray bottle pour it in & spray where I don’t want them it works great.
