A beehive entrance which encourages honey bees to bend forwards at an angle articulating their bodies as they go up and over a horizontal ridge 1. As they do this any Varroa mites clinging to the bees become exposed and are pulled off by horizontal fine threads 2 fixed above the ridge. The mites drop down through a permeable floor 4 into a collecting area 5 below and are caught in a sticky substance. Preferably the entrance incorporates a number of barriers 3 to deflect downwards any mites propelled away from the bee.
