Common Sense Pest Control
Common Sense Pest Control, by William Olkowski, Sheila Daar, and Helga Olkowski (Taunton Press, 1991; $40), is one of the most straightforward texts I've seen on controlling pests in the safest way possible. It covers both garden pests and household pests, something you don't often see in one volume. It gives details about life cycles as well as habits so you can choose your method of control with a strong background about the pest.

The Chicago Botanic Garden Web site, http://bestplants.chicago-botanic.org/, lists the best plants for use in the Midwest. Many are given trials at the botanic garden. The site contains beautiful photos as well as good cultural information.
