Diagnosis and bee health working groups

There are many factors that can influence the health of bee colonies, including diseases, diet and the beekeeping itself. Working groups actively support beekeepers locally in seven provinces in the Netherlands with advice and assistance for the health of their bee colonies.

These working groups can help you make a diagnosis in the event of bee mortality or breed mortality, but they often do more than just this.

How do I know if a bee colony is suffering from a disease or something else?

It’s not always easy to determine if a bee colony is suffering from something. Sometimes clear symptoms are visible, but sometimes they’re not. Dozens of dead bees by the hive does not have to be disconcerting.

Please contact the coordinator of the relevant working group if there is one operating in your province. You can find the contact information under the header ‘Is there a working group operating in my region?’ It’s not always necessary to send off a bee sample. Consult with the contact person to decide what your next best steps are.

I suspect that my bees have died because of spraying damage. What should I do?

If a large number of bees die suddenly or brood mortality occurs over a short period of time, there is a chance that this is due to spraying damage as a result of exposure to pesticides.

If you suspect spraying damage, please contact the NVWA via: NVWA.nl or call: 0900-03 88 (local rate)
