Thank you, Trees Atlanta, for bringing Dr. Doug Tallamy to town.
I know that he is here about once a year, and I am so grateful that folks in our city are regularly interested in hearing and heeding what he has to say. It was my first opportunity to attend a talk in person and to meet him, a delight! I am familiar with his books, with Homegrown National Park, and, of course, with his education on and advocacy for mosquito buckets. He has been both inspiration for and guide in my development of this bucket initiative in Decatur/Atlanta.
So I am quite familiar with Doug’s encouragement for us to plant and tend natives, even in small quantities, because they make a difference. His work influenced the transformations I started in my own yard a few years ago. I first learned from him the science of Bti and the strategy of mosquito buckets, their real possibility of controlling larvae and the relative ineffectiveness of spraying adults.
The multiple costs of abatement sprays are staggering, environmental and economical. I learned this week (not from Doug) that Georgia spends over $125,000,000 annually on mosquitoes and their effects, nuisance and disease. And that figure is, I believe, a few years old.*
I have written blogs about recent research on the drift of pyrethroid sprays and their toxicity to bees, which the Xerces Society for Invertebrate Conservation completed (in part in Decatur) in 2023 and publicized a year ago (see the video on our Resources page). But I learned during Doug’s talk last week about his own study on their persistence. Last summer Doug and students acquired a misting system, treated shrubbery, and examined its insect visitors. The pesticide application killed 26 species over 30 days. The results are not news, but the specificity—the duration and the numbers—are, at least to my knowledge.
It is my understanding that ULV (ultra-low-volume, but close to 100% active ingredients) mists have to contact the flying mosquitoes to kill them. And many of our local mosquitoes, the container varieties (they are seeking out collecting water around houses in recycling bins, bird baths, flower pots) are not out during the day. Sprays are a short-term solution with lasting consequences — even more reason to spread the buckets, Atlanta!
My heart is so full, even days after this talk. I appreciate Doug’s clarity and purpose. And because of him and others—many of you also in attendance on Saturday—I hold optimism that each one of us can make a difference, individually and collectively.
Thank you, Atlanta friends/advocates/gardeners. Thank you, Doug.
B THE CHANGE. B GOOD TO POLLINATORS.
*On Wednesday I sat for (and passed!) two exams to become a Commercial Pesticide Applicator, general standards and mosquito biology, surveillance and control. I have more to learn, but I feel so well informed our mosquitoes (63 species in our state!) and full of gratitude for the rigor of the process.
And I may make some upgrades to the buckets per some ideas that Doug shared. More soon.
