Yes. Pest control. Depending on where you live, if you have local rats and/or mice, they will find their way in. They love to eat wiring for some reason. I have had more than a few friends that took their car out of storage and found that all the insulation on the wiring was eaten off! For me, I adopted a bad a$$ cat that comes and goes, and I hate cats! But...no mice, rats or lizards anywhere and cheaper than a maid service
