Neonicotinoid Insecticides: Are Your Nursery Plants Being Treated With Bee-Killing Chemicals?

Several popular home stores are selling nursery plants treated with bee-killing chemicals, including potent neonicotinoid insecticides, also called “neonics.”

Unless you’re buying certified organic transplants this spring, you may be introducing persistent neonicotinoid insecticides into your garden — and thus into your food. As MOTHER EARTH NEWS has reported, neonics are potent systemic pesticides that spread through plants and contaminate pollen and nectar. The lingering poisons persist in soil, and they can be absorbed by subsequent crops. Neonics are one of the factors known to be contributing to colony collapse disorder, a phenomenon linked to the deaths of a vast number of honeybees over the past several years. These pesticides are also suspected of reducing many bird populations, as widespread use of neonics means fewer insects, which means less food for birds.

Neonics are widely used by farmers, and many garden centers and nurseries sell plants treated with them, too. This means you may be feeding neonics to your family, and bees could be poisoned by nursery plants you bring home. A 2013 study by the environmental group Friends of the Earth found neonics in plants from Lowe’s and Home Depot stores in Minneapolis, San Francisco and Washington, D.C. In Europe, the Pesticide Action Network tested more than 100 plant samples of crops such as strawberries, tomatoes and zucchini, and found neonic residues in several samples of each crop.

The neonic-producing chemical companies (Bayer and Syngenta) have convinced the U.S. Environmental Protection Agency that these insecticides do not pose a danger to humans. We, however, aren’t so sure. The chemicals’ effect on brain cells is similar to that of nicotine, and nicotine exposure is a known cause of adverse effects in children. A 2012 Japanese study concluded that neonics may pose potent risks to human health (visit the Public Library of Science to read the study).

We believe these insecticides should be banned, period. Europe has already done so temporarily for some neonics. Hats off to U.S. Reps. Earl Blumenauer of Oregon and John Conyers Jr. of Michigan for introducing the Saving America’s Pollinators Act, which seeks to suspend the use of neonics on bee-attracting plants.

We all know that bees are important for nature and today, we are finding very fewer bees for our environment which is really a bad news. If people are planning for pest control services they should opt for exterminator upper east side NYC (, which provides an organic form of pest control.

I bought flowers from Home Depot and Walmart. How do I get rid of the pesticides that are on my flowers?

BEWARE! I also have been HAD by HOME DEPOT!! I purchased 10 blueberry bushes and when planting in the ground, one of them had a tag inside the root ball fall out.....NEONICOTINOIDS! and proud of it, the tag reads"These pesticides are approved by the EPA". I didn't even see the tag in the others already in the ground. It would seem we have no safety nets in this crisis, and our responsibility to the pollinators will be a hard-fought battle with deception, financial greed, and the ignorance of those who choose to take refuge in "approved by the EPA."

HOME DEPOT IS ENGAGING IN DECEPTIVE MARKETING. Home Depot promised that they were going to label neonic-treated plants. I bought two Vigoro cherry trees from Home Depot Thursday. I LOOKED for any mention of neonics on the package; seeing none, I bought them. Only AFTER I had unwrapped the root ball and the loose soil had fallen into my amended soil in the hole, did I find the little plastic neonicotinoid tag, packaged INSIDE THE BURLAP. Neonicotinoids survive in the soil for 3 years -- some say 6 years or longer. They are water soluable and moves through the soil. They poison earthworms. Of course, the soil around the root ball fell into my hole, and I had to try to get all of that soil out of the hole and bag it, to return along with the trees. Vigoro is owned by Home Depot. It was no accident when they placed those tags where customers can't see them until the packaging around the roots is removed -- at home, after the hole is dug. I'll get my money back. I also recommend that when you shop at HOME DEPOT, take the tree or bush out of the pot, open up the burlap and look for that little green and white plastic tag.

Neonics can persist in soil for 3 years, maybe longer.

I starting buying plants from Home Depot in 2004. I am also wondering if I should remove all the plants and start over? If neonics are a systemic pesticide, are my old plants still toxic to bees? I am tempted to dig them up and return them to Home Depot, but I understand HD is going to label the neonic treated plants by the end of this year.

Hello. Just a question. If I bought some Fall plants last year at one of those big box stores and they contain that neonicotinoid poison (I’m hoping not, but lets say they do). How long will that last on my soil? I’m trying to go as organic as possible, meaning our lawn this year will go with no fertilizers, no weed killers, etc. I’ll embrace our so called weeds, besides, my daughter loves dandelions anyway. I’m planning on planting more natives in our yard and get rid of a big portion of our lawn little by little. It will take time but I’m hoping for the best. But yes, I’m wondering how long that horrible stuff lasts in the soil, if anybody knows, please let me know.

Thank you for this article. Is there anyway for us to tell if the plants we buy have neonics on them? I don't have much luck growing from seeds all the time.

Easy to buy plants that have been treated with neonicotinoid poison, or genetically modified. There are no markings or labels about this, as if the producers are ashamed; as they well should be! W-mart, H depot, Low's, even supermarkets sell starts relatively cheap, but where do they get them? Buy local at a greenhouse, landscaping business, or farmer's market, and look for organic.

I've always preferred purchasing starts at the farmers market simply to support local, small-scale sellers. Avoiding these chemicals seems an even more important reason. No more starts from "mainstream" garden centers for me! I hope people pass this article along to their gardening friends. I think most people are in the dark about such troubling problems.
