The existence of collimated, high-velocity outflows from symbiotic stars is a relatively recent discovery. Thus far only twelve such systems have been discovered since the first was found in the mid-1980's. Neither the mass loss nor the mass loss rates from those jets have yet been determined. If they contribute significantly to mass loss, then they are an important new element in the mass-transfer and mass-loss evolution of those symbiotic systems. Mass loss and mass transfers have implications for whether those systems are likely candidates for Type Ia supernova precursors. The Spitzer Space Telescope has proved to be a highly sensitive detector of extended infrared emission associated with a wide variety of objects. We have undertaken the first Spitzer search for extended emission near jet symbiotics using Spitzer's IRAC detector. No extended emission was detected near the six systems examined. This places a strong upper limit on any emission at those wavelengths, and suggests that there may not be a large amount of extended material in the vicinity of those systems.
