Cyper TC only lasts about 90 days on the surface of wood, though it would not be recommended to make anything from the treated wood that would contact food unless you apply an appropriate sealant after.
Cyper TC should not discolor anything when mixed properly. If you are concerned about sensitive surfaces, then you can test a small inconspicuous area, or you can stick with a water-based insecticide. We have a great Carpenter Bee Control Kit here which includes spray, dust, hand duster, and plugs to fill the holes.
Cyper TC does not have poultry facilities or housing on their their label. There are other products for ticks that can be used around poultry housing like Onslaught. Please read over Onslaught label for complete instructions.
Cyper TC does have the potential to stain certain types of exterior vinyl siding, according to the product label, but there is no application information listed for use on fabrics or leather so applications to these areas is prohibited. The label does state, "During any indoor surface application, do not allow dripping or runoff to occur. During any application to ceilings of a structure, cover surface below with plastic shielding or similar material." Please always use as directed.
For treating above ground for termites, Cyper TC is mixed at 1.3 to 5.1 fl oz per gallon of water. For termite trench applications, please visit the Post Contstruction Treatments Section starting on page 8 of the product label.
