First of all, you need to know that bees die every day because bees are born every day. The problem is when the colony collapses, i.e. when the whole hive dies. There are several possible causes: lack of nutrition, problems with the queen (who stops laying eggs, for example), poisoning, disease, etc. By monitoring the hive with BeeGuard sensors, we can analyse the characteristics of this collapse, if it occurs, and thus determine the time and cause of the bee depopulation. If it is a health problem, the environment is not directly to blame. On the other hand, if one day 60% of the foragers don't return, it's obvious that the bees have suffered an external defect that can be dated. If the colony dies after 6 months of food shortage, we can consider that food stress has contributed to this situation. Based on these factual observations, it is much easier to implement actions to compensate, reduce or avoid the problem. For example, planting plant cover to flower during the period of deficit in order to compensate for the structural deficit in the environment. Contact us to talk about it.
