Hmmm, since I keep a box turtle in my garden, where she is patrolling, I have not seen a slug or snail. For that same reason my chickens are free range. Now if I could only get them to eat ants.

ok, I'll try it and report back.

I should say I did not discover yellow attracts insects. I got tired of battling the yellow sticky traps. Besides, on the sticky traps, I saw plenty of adult gnats, but not eggs or larvae.

This water and soap gets the eggs too. So I got tired of them sticking to me and the plant and anything else they touch. I decided to try an old method I used to use to catch fleas when I had a dog. A nightlight turned on at night in a dark room, all the fleas will jump towards the light. Let me tell you I caught thousands of fleas like this. Don't forget to put a white piece of paper under the dish. They see the white and jump for it.
