Carowinds Discussion Thread in Theme Parks, Roller Coasters, & Donkeys! Posted Saturday at 05:58 AM One of the issues with yellow jackets could be due to staffing shortages and things (tables, trash cans, etc.) not being cleaned as often as in the past. When I worked at a park we had one year we had a MASSIVE yellow jacket problem, and it was because the manager in charge of park services that year was lazy AF and didn't have them spray the insides of the trash cans with bleach water every few days like the previous manager had. I had to deal with guest complaints about them multiple times a day.
