Friends of the Earth conducted a pilot study to determine the extent of neonicotinoid contamination of common nursery plants purchased at retail garden centers in cities across the U.S. 51 percent of the plants that were tested contained neonicotinoid residues.
The plants included in this pilot study were purchased from major nursery outlets and garden centers including Home Depot, Lowe’s, and Orchard Supply Hardware in three different locations across the country: the San Francisco Bay area of California; the Washington, DC area; and the Twin Cities area of Minnesota. (News Flash--Lowe's to stop selling neon's over 4 year time slot and Home Depot said it would label its plants with neon's ) See: http://www.nbcnews.com/science/environment/lowes-announces-ban-bee-killing-pesticides-n338631
The European Union suspended the use of three pesticides containing neonics in December 2013 after a
scientific review by European Food Safety Authority found that neonics pose an unacceptably high risk to bees. Unfortunatley, despite mounting evidence linking neonics to bee declines, the EPA has delayed action until 2018.
There are approximately 300 insecticides products containing neonicotinoid insecticides as active ingredients. The specific active ingredients include acetamiprid, clothianidin, dinotefuran, imidacloprid, thiacloprid, and thiamethoxam. Some of these same products go by different distributor names, such as the Ortho TM brand or other brand names. Inspect the label of any insecticide labeled as"system" for the presence of neonicotinoid active ingredients.
Pyrethroids now constitute the majority of commercial household insecticides used widely in home insect-control products, including flea bombs, roach sprays, ant bait, flea-and-tick pet shampoos, and lice shampoos. Aside from the fact that thay are also toxic to beneficial insects, such as bees and dragonflies, pyrethroids are toxic to fish and other aquatic organisms. At extremely small levels, such as 2 parts per trillion, pyrethroids are lethal to mayflies, gadflies, and invertebrates that constitute the base of many aquatic and terrestrial food webs here in San Juan County and the Pacific Northwest.
Furthermore, pyrethroids have been found to be unaffected by secondary treatment systems at wastewater treatment facilities, meaning that they appear in the effluent, which in the Northwest is often directly into the sea, usually at levels lethal to invertebrates. Pyrethroids can be particularly lethal to bees, cats, and fish and are toxic to humans and dogs. In humans, the chemicals can harm the nervous system, and high amounts can cause headache, difficulty breathing, nausea, and vomiting. The Environmental Protection Agency (EPA) has found that the pyrethroid permethrin is likely to be carcinogenic to humans.
Although they are modeled after naturally occurring insecticides (pyrethrins) found in chrysanthemum flowers, pyretroids are generally longer-lasting in the environment and are more toxic than their botanical cousins. Examples of pyrethroid pesticides include: cypermethrin, permethrin, deltamethrin, bifenthrin, and cyfluthrin.
