Nightmare! Found what looks like termites in my wood shed. Help!

[srinivas]

Hey everyone, hoping for some quick advice. I was getting out some firewood from my backyard shed and noticed a bunch of tiny, discarded wings on the floor. When I looked closer at one of the support beams, I saw what looks like mud tubes snaking up the side and the wood sounds hollow when I tap it.

I'm 90% sure these are termites. I'm freaking out a little. What should be my first step? Is this something a handy person can tackle themselves, or do I absolutely need to call a pro? Any recommendations for a good termite controller would be great too (I'm in the suburbs, if that helps).

Thanks in advance.
