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."
