Chemical poisoning




In modern agriculture, chemical agents are used to protect plants from diseases and pests. Some of them are dangerous for bees.

Farmers are obliged to inform beekeepers when they will start spraying or pollinating plants, so that beekeepers can protect their bees.

When the beekeeper finds out on which day the spraying or dusting of plants will start, he should close the hive early in the morning, even before the bees start to fly, and open the ventilation devices as much as possible.


If the bees will be closed for a long time, they should pour water into the feeder or into the empty honeycomb. If it is too hot outside, then the bees should be transferred to a cooler room and kept there until the danger passes, and then returned to their original place, strictly taking care that each hive is placed in the place where it was before entering. Otherwise, there would be a lot of confusion and other damage.


While the hives are closed, the bees must not be disturbed at all, and they should not be fed. How long the bees will be closed depends on the type of chemical agent used, or how long the toxicity of that agent lasts.


  • The action of arsenic and fluorine preparations lasts for three to five days
  • The parathyroid preparation ceases to be dangerous after three days
  • Nicotine agents, herbicides, mineral oils and other similar agents are toxic to bees only a few hours after dusting or spraying

If heavy rain falls after spraying or dusting, the danger to bees almost ceases. Also, when there is a strong wind or strong heat, and the temperature in the shade is 30 ° C, the danger to bees passes faster.


Beekeepers should contact farmers, the municipality, chambers and associations in order to find the best solutions to protect both plants and bees. Without constant and direct contact and cooperation between beekeepers and farmers, as well as the mentioned institutions, it will be difficult to achieve favorable results in the protection of bees from chemical plant protection products.
