WASPS

Wasps, hornets, and yellow jackets will sometimes kill bees at the entrance to the hive or out in the wild.

SOLUTION

The best way to deal with them is to find and chemically destroy their nest. Alternatively, you can move your hives away from the nest or use an entrance reducer to help the bees guard against their attackers.
