In the summer of 2017 T.A.P. insulation was installed over a portion of the IPM House attic. The installation was done after the old fiberglass batting insulation was first removed. This video shows the process and explains a little about the insulation.
Texas A&M AgriLife has not thoroughly tested the effectiveness of T.A.P. insulation for pest control, but the borate compounds used in the product are known to impart fire retardant properties and pest control (as stomach poisons).
