It has been five years since we built the first Bushkill Bee Vac. Hundreds of Bushkill Bee Vacs are in use by professionals and hobbyist, and are serving them well. Although the Bushkill Bee Vac is a superior design to any other bee vac on the market, we have made some improvements based on our experience and feedback from our users.
Our latest version has the following enhancements:

bypass Larger bypass-valve
As available vacuums become more powerful, it has become clear that the bypass-valve needs to be increased as well.
IMG_1023 Improved cut-out shim design
New plastic insert is easier to install and remove. It is also much more durable than a hardware cloth insert. Addition of center support also eliminates the possibilities of insert collapse from weight of clustered bees.
IMG_1019 Multiple options supporting integrated and stand-alone vacuums
The bee vac now supports many models of detachable blower wet/dry vacs as well as external support of any wet/dry vac with 2-1/2″ hose. The complete list (current and older models) of wet/dry vacs supported for integrated mounting can be found here.
