About Jessica Walliser
In 2008, Jessica Walliser revolutionized backyard pest management by documenting, and rigorously testing, the first regionally adapted 'insectary planting calendar' for the northeastern U.S., proving that strategically timed blooms of yarrow, goldenrod, and buckwheat could increase lacewing populations by over 300% within a single season. Her fieldwork didn’t rely on lab-controlled trials but on 17 years of side-by-side plots in Pittsburgh backyards, measuring parasitism rates, aphid colony collapse timelines, and pollinator visitation frequency with hand-held tally counters and digital microscopes. She co-founded the Pennsylvania Pollinator Protection Plan’s residential outreach arm, translating entomological research into shovel-ready advice: not just *which* plants attract hoverflies, but *when to shear them*, *how much bare soil to leave*, and *why mulch depth matters more than bloom color*. Her writing rejects the myth of the 'perfect garden', favoring observable cause-and-effect over aesthetic dogma, her most cited paper analyzes how neighbor-scale pesticide drift reshapes local hymenopteran communities, even in certified organic yards.
