Here's a few remedies, http://www.ehow.com/how_2095512_get-...unk-smell.html. I have used the peroxide one with good results. Onr night out house got "skunked", we had the windows open and the smell woke us up at 3 AM, WOW was it bad. I mixed up a batch with baking soda and peroxide, and put it on a cloth over a fan filter, and ran the fan. It really took the smell out of the house, in just a few minutes.

I'd mix it up and use a spray bottle and give the trap a good dose of it.
