Here is a link to find or create a petition in your area to put pressure on True Value to stop selling neonics:
Thanks to all of you who are helping in this effort. Beekeepers working to go treatment-free can get good genetics into bee populations (the bees are helping us with this!), but they can’t get bees to survive when they are being poisoned. This is especially hazardous when the general public buys flowers unaware.
Do not buy the new fall flowers at the Bi-Mart in Eugene . They come from Spring Creek Nursery and have been treated with neonics as young plants. I was told by the personnel at Bi-Mart that the nursery assured them that the neonics are all gone by the time the flowers are purchased and planted. But we know this is not true. Neonics are systemic, which means they remain in the plants , and every cell of that plant delivers poison to the bees who visit it.
Folks at this worker-owned store and customers who buy there are given misinformation or no information at all in this respect. My dear elderly neighbor across the street who loves bees fills his garden with store-bought mums, which may or may not be poisonous to the bees he wants to help. I must admit I have not the heart to ask him where he gets his flowers.
Here is what you can do about Bi-Mart, as a sympathetic employee told me. Mail the “Did we get it right?” pamphlet with your protest of the use of neonics to the district headquarters. Don’t leave it off at local stores, as they have no power to change this.
Currently there is little nectar available for local bees, so they will readily come to that small patio pot. Make sure it does not contain bee poison!
Every time you purchase a blooming flower, be sure to ask whether its supplier uses neonics. Good news in our area is that Peoria Gardens does not use these– and supplies Grays and Down to Earth. And as documented here, Home Depot and Lowe’s are planning to eliminate them. Wilco Farm Store’s suppliers also do not use neonics.
Thank you to all who helped to make this change.
This class action lawsuit, filed in Ontario Superior Court, asks 400 million dollars in damages stemming from the losses to beekeepers caused by neonicotinoids manufactured by these corporations.
The goal of this lawsuit is to stop the use of these bee-killing pesticides.
Thanks to the Canadian beekeepers for taking a stand not only on behalf of all those who keep bees, but those who rely on bees for our food (that means all of us!)
What started out as a bit of curiosity about the time-dependent toxicity of insecticides led to a blog piece I did a little over a year ago titled Time-dependent Toxicity of Imidacloprid in Bees and Ants. I thought my results were interesting enough to get a comment from other scientists that were looking at the time-dependent toxicity question so I sent out the link to a few. With the encouragement of especially Dr.Fransico Sanchez-Bayo at the University of Sydney in Austrailia, I went ahead expanded the research and we turned that blog post into a paper. I am especaily grateful to my co-authors, especially Fransico Sanchez-Bayo and Nicolas Desneux, who shepparded the manuscript through the journal submission and review process.
So please take a look at the real thing. We were published in Nature’s online publication Scientific Reports.

Research out of the Netherlands, to be published tomorrow (7.10.2014) in the prestigious journal Nature, demonstrates a strong correlation between the decline of insect-eating bird species and presence of neonics in the environment. Comparable declines in bird species did not take place in the same areas before neonics were used, nor does it take place today even on farmland where bird habitat is undermined but neonic contamination is lower. Co-authors Caspar A. Hallmann, Ruud P. B. Foppen,Chris A. M. van Turnhout,Hans de Kroon & Eelke Jongejans speculate that neonics deplete food sources for several bird species through the sustained poisoning of non-target insects:
“Our results suggest that the impact of neonicotinoids on the natural environment is even more substantial than has recently been reported and is reminiscent of the effects of persistent insecticides in the past. Future legislation should take into account the potential cascading effects of neonicotinoids on ecosystems.”
In the wake of two recent bumblebee die offs in Eugene and Portland resulting from pesticide poisoning, it is especially important to report suspected pesticide poisonings to the Oregon Department of Agriculture.
If you are a beekeeper who finds more than 50 dead bees in any single area or colony, contact the Oregon Department of Agriculture: firstname.lastname@example.org or (503) 986-6466.
