I mix 1cup of mouthwash (mint is Good)
1 cup alcohol
1 tea spoon dish soap
1 litter of water
Mix well and spray with a sray bottle making sure you get under the leaves
Works real good for me on all those tiny varmits you can't hardly see.

I also use 1 head of garlic
2 halapinos
1 large onion
1/2 gal water
Blend in the blender and let it sit over night, put thru cheese cloth and pray, this is especialy good for any kind of worms.
Word of caution...Your yard will smell very edible but it works
Let me know if this works for ya :o)
