Hello.
I am looking for diy plans for tube traps.

Here's the plan.  Make a cylinder of hardware cloth or similar wire, as large as space will allow.  Fill it with fiberglass. Cap the ends, and cover with some high WAF, but loose weave material.  Stack to reach the ceiling and place in room corners.

Hello.
I am looking for diy plans for tube traps.

YOu can also get some large Sonotubes and cut some slots and random holes in them to get close to what Mr Clark was suggesting.

Or, paradigm shift, they can be rectangular or triangular to fit into the corners.

Any more detailed plans such as using rigid fiberglass insulation tubes which are original designed to wrap and cover large diameter iron pipe? i.e. 13” or 16” diameter in 3’ length which can also be stacked?

Here's what I did.

For each tube trap, I used two of these (3’ x 16 ¾” fiberglass pipe insulation).

I removed the wrap on half the circumference and left it on the other half. This allows you to get some diffraction from the front of the tube traps while absorbing from the back.

I wrapped these two pieces with ¼” steel cloth (like you’d use for a rabbit cage) from home depot to hold them together. The steel cloth also helps keep the form.

I then wrapped them with Guilford of Maine FR701 fabric. I folded over and sewed the overlapped edge so it would provide a nice finish, and used a hot glue gun to secure everything.

I purchased 12.75 diameter x 3” foam rounds from buyfoam.com and inserted one of these in the middle and one on each end. This helps keep the fiberglass insulation nicely shaped and also holds the fabric tight. 

I bought some ¼” thick wood rounds (found them on Amazon) which I wrapped with the fabric and glued to the top and bottom.

I see. I like the idea of round fiberglass pipe tubes. I found a manufacture in town. Allied Insulation. Very helpful.

There are plenty of recipes online.
