告诉你怎么办:

1. You can treat the fence(all exposed surfaces) with chemicals. E.g. http://www.allpestexpress.com/timbor.aspx
I don't think you have treated wood fence, so you might have to repeat it every year.

2. Tighten up the nut on the valve. I think the valve itself is still good.

3. Buy a roll of aluminum tape (for heating ducts) at Home Depot (about $5-7) and seal the leaks.
