Many insects are attracted to IR sources because the insects use it to detect a warm body for food, egg-laying hosts, etc. Mosquitoes and bed bugs included. Even some mammals use similar methods to detect prey.
Are you tying to use IR to trap the little buzzers? I think it's probably been tried before because it's quite well known. I guess that the wavelength might be important.
