Wow...... Just, wow....As a ex tech I can tell you right now that I didn't deal with bee's no matter how much the customer complained! PERIOD!
I would reschedule till they resolved the issue. If I could put a new dish up some where else with ease and less than 20 mins then MAYBE I would do that otherwise nope. See I was paid per job not per hour so the faster you were in and out of the job the more you were paid...messing with bee's not only slowed me down but was also just flat out dangerous.
Some of the guys mentioned sprays they had...but at the end of the day NOPE.
I was a dish tech NOT an exterminator!
