Has anyone seen that 80's crappy movie Ants! (not the newer animated one). It is about a hotel and millions of killer toxic ants take it right over and they are swarming everywhere. It was one of the most traumatic things my 8 year old self could have ever watched. It still haunts me to this day.
These ants are at Restoule Provincial Park
Here is a brief review of the actual movie Ants!
