From the National Garden Club:
It has been brought to my attention that some “Big Stores” have been selling Milkweed plants that have been treated with systemic Neonicotinoids. This will kill caterpillars! Please, be aware and be on the lookout for these tags placed in plants.
The letter below is from a fellow garden club member:
After purchasing a Milkweed plant from Home Depot near my home I noticed on the little information stick hidden behind the identification information that the plant had been treated with systemic Neonicotinoids. The container boasted how desirable the plant is for birds and butterflies. Yesterday I went to a different Home Depot and they had just put out an entire rolling cart of these plants, maybe about 100, all poisoned. I contacted the store manager and told him that it is the same as giving poison candy to kids on Halloween. This is THE host plant for the Monarch. My club, Shady Oaks and our junior club, Little Shadows have worked so hard to establish a Monarch Waystation and to educate people on the decline of the Monarch. I hate to think of the millions of poison Milkweed being distributed nationwide by Home Depot.
The container says distributed by Home Depot, 2455 Paces Ferry Rd N. W., Atlanta, Georgia.
I contacted the LSU Ag Agent for New Orleans, Dr. Joe Willis. He said the Neonicotinoids will dilute as the plants grow but that only a very small amount will kill the larva of the Monarch.
