How do I get rid of bugs living in my oven for good?

It seems bugs have made a habitat out of our rarely used oven. We see them coming in and out of it and I have a feeling the hard to get to nooks and crannies of the oven are perfect hiding places for these sonamvaguns. Have you ever tried going after bugs living in your oven? Of course we would try firing it up but I just want to get info if this would work and maybe get tips on how to make sure it works. Thanks!
