Bora-Care & Shell-Guard
Bora-Care (Nisus Corporation) and Shell-Guard
(Perma-Chink Systems) are borate-based wood
treatments for the prevention of decay fungi and
insect damage. Both products use glycol* to increase
the penetration of the borate preservative into wood fibers.
As insecticide/fungicides both Bora-Care
and Shell-Guard are labeled for use against termites,
wood-destroying beetles, carpenter ants,
and wood decay fungi (dry
rot). Both are very effective against many of
the most important wood destroying organisms and
exhibit relatively low toxicity compared to other
pesticides.
Common misspellings and common names:
Boracare, Shellguard
*Bora Care contains ethylene glycol
while Shell-Guard contains a less toxic form of glycol
called propylene glycol.
