I’m sure you’ve noticed on facebook, postings to the effect of “The secret Insurance companies don’t want you to know….” or “The secret banks don’t want you to know…” and so on. Well here’s a secret that pesticide companies don’t want you to know…..worm castings. I’ve been using worm castings for years to control white flies, all you have to do is scatter just a little on top of the soil and white flies will disappear. As an added bonus worm castings are a natural fertilizer and soil amendment. Double the value for your money and effort!
