WorriedWoodworker, listen carefully. Do not attempt to treat this yourself.
The presence of wings and mud tubes almost certainly confirms subterranean termites. The shed is just the "food source" you can see. The colony itself, with potentially hundreds of thousands of termites, is in the ground nearby.
A DIY foam or spray will only kill the termites you can see, acting as a temporary repellent. It does nothing to address the main colony in the soil, which will just find another path into your shed—or worse, your home.
Your first step is to get a professional inspection. Most reputable companies offer them for free. They will assess the damage to the shed and, crucially, check your home's foundation, crawl spaces, and attic for any signs of activity. Termites can cause extensive, hidden damage before you even know they're there.
I cannot stress this enough: The cost of a professional treatment is far less than the cost of repairing structural wood damage to your house.
