Why I should never clean under the fridge

O.K. I'm only slightly embarrased to admit that, in the almost 7 years that we have lived in this house with this fridge, I had never completely moved the fridge out of its little spot and cleaned under the whole thing. (I had also never vacuumed the "coils" underneath.) But a week ago, I got in a real cleaning fit, and I decided to finally do it. The dustball by the coils/vent/whatever it is underneath was seriously the size of a small cat. Ick. Then I moved the fridge and discoverd some dirt & small items that had fallen, and then a red sticky spot that was about 8 inches around. It appeared to be some sort of punch. I don't remember the last time that we had punch, much less red, so it had to have been there awhile. Amazingly, I found no ants or evidence that there had ever been ants under the fridge.

So I cleaned the floor, moved the fridge back, and felt super proud of myself for finally cleaning under my fridge.

And then this afternoon, I went upstairs to get something out of the kitchen. My shoes immediately starting sticking to the floor, in the area in front of the fridge. And there was a lid on floor. I opened the fridge, and apparently one of my darling children had spilled a whole container of juice (apple juice, so at least it didn't stain) in & in front of the fridge. And under the fridge. I hadn't cleaned it for 7 years, and now 7 DAYS later, there is a reason to clean under there.

So should I wait another 7 years to clean up this spill?
