Marty was our lead horse that August afternoon. All of the sudden he started stomping the ground! Bees!!! Sherry tried to get him to go, but he just wanted them off and kept stomping. The bees were everywhere! Susanne and I, not being able to help Sherry and Marty, turned and got a safe distance away from the activity. Susanne's horse "Lolita" had already been stung several times. Sherry finally got Marty to move, but the bees were still coming after him. We ran up the trail quite a ways until they left. After all that, Marty had over 50 stings and Sherry had 3. We were worried about Marty having a reaction to all the stings and decided to get off and walk back to the staging area. We pulled the stingers out, taking care not to squeeze them which would inject more of the poisons. Marty did not have any reaction other than being covered in welts. By the end of the day, the welts on Marty were 3 times the size of the ones pictured. He lost his hair on the welts, but survived. My veterinarian said that if he gets into bees again, he could quite possibly have a severe reaction. Now, during bee season, I carry Epinephrine and syringes in my saddlebag. We think that these were bald hornets and not ground bees. They were larger than bees.
