Disease Inspection – Brood

It is good practice to carry out regular checks for brood diseases, at the very least once in Spring and again in the Autumn.

To check the brood
live bees need to be brushed or shaken off the combs.IMG_1020 (800x533)
To shake bees off a frame first remove one or two frames which do not contain brood from the edge of the brood box, so that you can make space. When you get to a frame with brood on it, hold it firmly by the lugs with most of the frame still suspended inside the box, and give it a short, sharp jerk down to shake most of the bees off and into the box rather than up into the air.


NBU Best Practice Guideline No.2 –
Handling and Examining a Colony of Bees
Learn to recognise healthy brood
– both capped and uncapped – so that you can spot when any looks abnormal.

Know what you are looking for
If you find brood that looks abnormal it helps if you already have an idea of what conditions and diseases you might find and what to look for.
