There are a number of reasons bee farms fail, but the most common one is pests. Bee hives can be susceptible to a variety of pests, such as wax moths, small bee hive beetles, and Varroa mites. Without proper management, these pests can quickly overrun a hive and kill the bees. Disease is also another common problem for local beekeepers, and can wipe out an entire hive if not treated. Poor weather conditions or a shortage of food supply can also cause bee colonies to die off.
