If you brought any unwelcome freeloaders in with your plants this fall, I have a great safe way to deal with them. I'm not sure where I saw this, but for years I've been afraid to spray pesticide indoors because of my pets. So, to treat any insects that may have come inside on my plants' leaves, I place a flea collar around the base of the pot. After a few days, I move the collar to any plant that looks like it's in trouble.
It works like a charm. Many of the outlet stores carry private label flea collars that are very reasonably priced.
This method is safe for your animals and also for you. Change out the collars in spring and fall, and you can rest easy. Give it a try.
