That video is mostly correct. BTDT. I was the state certified pest control operator in charge of Resorts Pest Management and an area manager at Dismal for 11 years. We did, however, spray the schit out of that place! Additionally, tons of Altosid larvicide was used yearly. The pest management department(s) were 24/7/365 operations. I had 56 operators working for me in Resorts. The Parks side had almost as many. Eventually, the Parks and Resorts merged into one big department. It was a unionized shop... which oftentimes led to difficulties.
