This movie handles about a wasp-invasion in a little town called Dundas, Indiana. I'm not sure if the town has a high-school football team, but if they do, they should rename themselves the Dundas Yellow-jackets and adopt a guy in giant wasp suit as their mascot! Just an idea...
"Swarmed!" is a typically made-for-TV killer-insect horror flick from the early 2000s. That doesn't automatically make it terrible, it simply means you must take into account a few standard shortcomings, like clumsy and cheap-looking CGI effects, derivative storylines, barely any (intentional) humor, and pretty poor performances.
A local research institute experiments with a new type of pesticide against yellow-jacket wasps, but it doesn't really work as planned, since the liquid makes the critters even more aggressive and their first sting deadly already. As a matter of course, bottles accidentally get mixed up, and a killer swarm of yellow-jackets heads towards town to partake in the annual BBQ-contest.
There we have the inevitable "Jaws"-copy! The mayor, sponsor and chief of police obviously refuse to cancel the town's big publicity event, and they'll live to regret it! "Swarmed" is a silly and insignificant creature-feature, but fun enough to watch once thanks to a couple of hopelessly idiotic moments. There's a notable sequence in which the mayor's secretary goes after a single wasp with a shotgun, and for some reason the wasps seem to specifically target the "bad people". While hundreds of people are running around and form easy targets, the yellow jackets prefer to kill the sponsor who ingeniously hid himself in a barrel of water. Smart wasps!
