If the playhouse is sitting on the ground, then the first recommendation is to get it off the ground. When the wood contacts the ground it creates what is called "earth to wood contact" and stopping termites is difficult - even with Taurus SC or Termidor.
I would recommend to use pavers or cinder blocks and then use new runners that are pressure treated to sit the playhouse on.
You can then treat the soil around the pavers or blocks with Taurus and the problem will be solved.
If you can't do the above, and treating is your only option, then use the "spray and pray" method. This would be to dig a trench around the perimeter of the playhouse and next to the runners several inches deep and apply Taurus SC into the trench. The rate of application is 4 gallons per 10 linear feet. When the trench / soil is saturated, rake the soil into it and smooth it out.
Drilling holes through the bottom of the floor and "blindly" spraying Taurus under it, might work, but I wouldn't bet on it. It would take a lot of Taurus to do this, a lot of drill holes and then you have what could end being a chemical dump under the playhouse. I would be a little concerned about kids playing in it.
My advice would be to think bout the correct way to do this, and not simply spraying chemical around and under it. If you do it properly, this will solve the rot problem and the termite problem for years.
