While installing a K&N airfilter yesterday, I found evidence (and quite a bit of it!)that mice had been vacationing in my "new" 940's airbox. The material didn't look to be recently deposited... but I want to "lock" 'em out in the future!

Has anyone installed screens in the intake duct? Searching this forum, I found references to mothballs. What about a few mothballs left to rattle around the bottom of that big airbox? Any problem with that? Recommendations are appreciated. The car is now driven daily... at least 90 non-stop highway miles. You would think that would slow 'em down... or at least make them car sick! Hmmmm... but come to think of it, my sister-in-law probably drove the car daily before I got it.

BTW... the car came from the "big city suburbs" and it was garaged daily in a near "spotless" environment. My brother and wife and clean freaks! So... they can be anywhere. I can't wait to pull my brother's airbox lids to see what he might have in his other two Volvos! He's not a DIY guy... probably has never seen the inside of the airbox.

Thanks...
