This copy of "Common Sense Pest Control" by Helga Olkowski is a pamplet with 1971 copyright date so I'm assuming it's an earlier edition of her 1991 "Common-Sense Pest Control Least toxic solutions for your home, garden, pets and community."
Pests And Pesticides: Fact And A Philosophy (A Guide to Home Pest Control) is a booklet that a Community Pest Control Subcommittee prepared in cooperation with the City of Palo Alto.
