Silly
All Disney would have to do is show their normal efforts on the bug front.
They nuke the place every night for bugs. They have trucks hit every byway, parking lot, etc with fog and they spray every inch of the parks and resorts.
We lived in Orlando for a while and having only had WDW experience prior to that, we were stunned at the number of crazy bugs we saw around our place every day. Mothra, ants with red velvet on them, 5in beetles being carried off section at a time by colonies of creepy crawlies.... flippin' disgusting.
All I have ever seen on property are the occasional lovebug, lizzards, and a feral cat in the Jungle Cruise.
Seriously, have you ever had a bite? I haven't.
