I have used DiPel for years, a little goes a long way. I love my conical shrubs and trees, but sometimes they get bagworms. One spray usually gets rid of them all. It is not so easy to pick bag worms off a 12 to 25 foot tree, so I put the Dipel in a sprayer and spray them. It is comforting to know that this insecticide does not harm the beneficial insects or the wildlife, including birds, butterflies, etc.
I am a Bee Keeper and store my Supers for the winter.
The Supers have drawn out Comb which Wax Moths like.
They will tunnel and destroy honey comb being stored.
I spray each side and stack them 5 high and cover with a hive top.
I don't have any problem with Wax Moths when using this product.
This chemical is also naturally found in Honey and is not harmful to the bees.
I just let the supers air for 3 days before putting them on a hive.
Dipel wettable powder is the most economical, effective and long storing alternative for delivering Bt (Bacillus thuringensis) where you need it. Stored properly, it keeps for years. I used it on my sweet corn this year, and it produced almost 100% control of corn earworms. Also used it on my broccoli, which is almost impossible to grow here in the south without Bt to keep cabbage wing moths and loopers under control. I highly recommend this product.
