Per from East, Nj writes,

Can Dominion be sprayed on floor joists

There is termite activitie in floor joists which are cover by a drop ceiling in the basement. Can Dominion or Termidor be sprayed on the wood? Or should the trench treatment be done first and then followed with Boracare?


If you see galleries the termites have eaten away in the floor joists you can spot treat directly in those galleries with Dominion or Termidor. However if the direct galleries can not be accessed, spraying the wood would not be recommended nor helpful as it will not penetrate into the wood. Do a soil treatment with either of the products, give it 90 days to eliminate the colony, then treat the floor joists with Boracare for a life long prevention on the wood.
