How can I open up my Panasonic breadmachine SD-253?

I have discovered small white larvae (yuk!!!) creeping out from the machine when it is on (no activity when it is off) and I don't know whether the eggs were laid in the lid or in the part with the little window. How can I get into these two parts to clean them out. I have had the machine for at least 5 years and it has never happened before.
