I think it is. i usually shoot enough of it in the hole to flood it. I figger they will drown in the oil.
I use oil based finishes so i don't have to worry about the Wd.
I use they spray on small holes and air on large ones.
I have used sanding sealer on some pieces that i forgot to deal with. They didn't get backed all they way out the hole. they were dead with their back side hanging out.
