Re: Apivar Treatment Timing
Just to add to what the others said, Apivar will do you little good on plain foundation, iirc, the instructions say it MUST be in the brood area to expose as many nurse bees as possible to be effective.
Since Apivar is a contact Rx, the nurse bees walk on it and disperse it, where as Rx such as Apigaurd are a gel type that bees actively remove, thus tracking it around the hive.
