Director Gary Jones got his start in special effects and even worked with the likes of Sam Raimi on both Evil Dead II and Army of Darkness before turning director with Mosquito. So, there's little wonder why the effects are pretty outstanding, and the film has a certain kinetic energy and flow that can really only be compared to the Raimi and his Evil Dead trilogy. The effects, which are mostly practical, consists of a combination of stop-animation, puppetry, traditional cel animation, and miniatures, with a few computer generated bits sprinkled here and there. The CGI aspects are obviously outdated and are the worst bits about the film, but the practical mosquito puppets and effects still look pretty damn good today.

This would probably be a different story had the film came out a few years later after the practical effects heyday, so I'd like to pause in a moment of remembrance for the 90s impressive practical effects before the massive shift to predominately CGI post 1997.
