To anyone who relies on Bio Flea Halt to help control the flea
population in their yard:
FYI, I discovered that Bio Flea Halt CAN go "bad". I opened our canister
yesterday to put some on the lawn, and the whole can was full of MOLD! I
called the 1-800 # on the can, and the operator said that if it's moldy,
the little nematodes are probably all dead.
