Apiguard has been used in Europe for almost 30 years with no evidence of resistance.
That´s a good news.
By the way, it is better Apilifeguard.
It is good to have any bullets for the future.
I know that is wonderful. Apiguard is in the same ball game as Oxalic and Formic Acid. Totally different than fluvalonite and coumophos, which bees build up resistance to. Best of this beautiful day. Cindi
