# What pest control works on caterpillars, flea beetles, and leaf…

What pest control works on caterpillars, flea beetles, and leaf miners all in one?

\-

From research, I hear spinosad works as well as neem oil, but money is tight right now so I want to know what I'm buying before I buy it.

For now, I'm testing 500ml water + 1tsp Dawn + 1tsp Publix Vegetable Oil

This comes up when I notice holes in my kale plants and those white lines/tunnels made by leaf miners in my Baby Bok Choy, Snappy Peas, and Kale.

The image attached is from my DBCV Kale. I picked that leaf and the other ones on each plant off. Some by the stem. The Premier Kale tagged in this post is one of the two total that have the holes in them. They're growing well so I want to save them while I can.

What has worked for you besides just squeeze-killing the bugs and shooing them away?

I know BT (Bacillus thuringiensis) works on caterpillars. Spinosad help me with fungus gnats
