BERRYTON, KS (KSNT) - As we get closer to winter, it can be quite a struggle for beekeepers raising honeybees. The demand for honey increases around this time of year, and it also comes at a cost. According to a nationwide survey, nearly half of the honeybee colonies across the country died last year. KSNT 27 News spoke to local beekeeper Tim Urich, who said he loses at least 10% of his honeybees every fall. To help decrease that number, he uses an acid to prevent parasites like Varroa Mites from killing them.

"Losing a colony to the Varroa Mite or to a weak queen or just to starvation represents an economic loss to every beekeeper," Urich said. "But I found that when colonies are weak its best to cull them this time of year and combine those bees with a healthy colony." He told 27 News when doing this, it will make predicting the spring harvest much easier. For more local news, click here.
