Unintentional copy of the 1975 movie?
I have not seen this movie, only read about it, but it seems to me that it's pretty close to the plot of the 1975 movie, "Bugs", which was based on a novel.
IMDb page is http://www.imdb.com/title/tt0072750/combined
Of course, how many variations of a story about killer bugs can you write? If you've seen one, you've probably seen 'em all.
