Eggs left in refrigrator

We went camping in January 2015 and another trip was planned April 2015. When the refrigerator was opened about 5 rotten eggs were found. Also, there were larvae and small white worms. The smell is awful. We've tried charcoal, baking soda, and Knox gelatin to no avail. Does anyone know how to abated the smell and any other measures to kill any larvae/worms?
