Mallis Handbook Auction!

The special auction of individual volumes of Stoy Hedges’ collection of the Mallis Handbook of Pest Control launched in October and successfully raised $1050 in funds to support Pi Chi Omega's mission through the auction of the first three editions. We are re-opening the auction in hopes of finding a home for the remaining seven volumes that need an insect enthusiast's bookshelf to reside on.

The remaining items from this rare set include editions 4 through 10 of the Mallis Handbook of Pest Control, first published in 1945 and long regarded as the definitive “bible” of structural pest management. The volumes were owned and cherished by Stoy Hedges—a consummate insect enthusiast, educator, and honorary Pi Chi Omega member. Throughout his distinguished career, Stoy relied on these volumes and even served as editorial director for the 8th, 9th, and 10th editions - as well as the recently released 11th edition available through PCT.

Stoy passed away in December 2023 at age 64, following complications during heart transplant surgery. His wife, Kathy, generously donated his treasured collection so it could continue to inspire and educate others. She shared that Stoy deeply valued these books and wanted them to find a home with someone who would appreciate them just as much.

About the Collection

This auction offers an opportunity to obtain one or more volumes of the remaining volumes from the remaining set of the renowned Mallis Handbook of Pest Control, donated by Kathy Hedges in honor of Stoy’s legacy. The timing is especially fitting, as the 11th edition is set to release in November—making this a perfect opportunity for collectors to complete or enhance their libraries.

During his 25-year career as Senior Technical Entomologist with Terminix International, Stoy was known as the company’s in-house “answer man,” supporting over 4,000 technicians nationwide. His work and leadership helped shape modern pest management, transforming the industry from “extermination” to today’s science-driven profession.

Pi Chi Omega is a fraternal organization dedicated to connecting and enriching the urban pest management Industry. Initiated in 1950 by six students of Dr. John V. Osmun at Purdue University, the fraternity today is comprised of nearly 450 members representing 38 states and 4 foreign countries. These members are some of the most distinguished, dedicated, and talented professionals in the pest control industry. We welcome new members who share our passion for knowledge, education, and growth.

Since Pi Chi Omega was organized, a key focus has been on supporting formal education within the field of entomology, and related scientific studies. Each year Pi Chi Omega awards $13,000 in scholarships, to six deserving students. The object of the scholarship program is to encourage and assist outstanding students to prepare for careers in pest management. 

Pi Chi Omega also supports professional development through the recently developed Industry Grant Program for those connected to our industry. This program provides financial support to assist individuals seeking to enhance or expand their professional knowledge or seeking funds to develop and introduce new products or information to support the pest management industry.
