Today while doing shop work and listening to the radio on NPR weekend edition was an article on the pesticide problems and mites facing a Colorado beekeeper. Being the weekend these programs usually get played twice and you may be able to catch it on your NPR station NPR= national public radio stations are usually on the low end of the dial. Same story- piles of dead bees at the hive foragers sprayed or dusted- metion made of Penncap and Imodin or something that sounds like the name Imodin I am not too heavy on pesticides other than flea stuff for the dogs and apistan.
