For those of you who do not have access to oyster shells, Diatomaceous earth is also very good. If your gardening center does not carry it try a pool supply or a pet store that has aquariums, it is used in water filtration systems. It acts like razor blades on the tiny bugs.

Diatomaceous earth is also good for controlling ants. Spread it around the base of your house. It cuts them up the same way.

A friend also used it in her bluebird house to control blowflies and had a much better survival rate for the baby birds. She sprinkled it around in the nest.
