We propose a MIPS 24 micron survey all short-period comets that will be bright during the 2004-5 observing season to search for large meteoroid production. The large particles will be dynamically separated from small dust particles in the wide-field images due to their different radiation pressure forces. Large particles are spread mostly behind the comet in a long, thin debris trail. The proposed survey will cover 25 comets and will help determine whether all comets produce large meteoroids. Large meteoroids are they dominant mass loss of comets, yet very little is known about them now. They are also important as potential hazards to spacecraft and are the same phenomenon as meteor showers.
