I haven't, but have certainly experienced driving through regions where there are still insects. Northern MN for example, that was reminiscent of what it used to be like driving through NE. That's besides the point though, at least along the route I drive most often, which is i80 between SF and Chicago, there's been a very visible decline of insects over the past ~1.5 decades according to the windshield gauge.
