Can insulation go over knob and tube?

The existing knob and tube wires could be covered with a box large enough to maintain three inches of air space around each conductor, and then insulation could be spread over that.This type of wiring system can be buried in insulation, and it does carry a grounding conductor for shock protection.

Can a junction box be covered with blown insulation?

What can I use instead of fish tape?

A fish tape is a thin, flexible steel tape, typically 1/4 to 1/2-inch wide, that comes on a large reel, similar to a surveyor’s tape measure. Heavy gauge wire can be used to create a fish tape. Much of the wiring in new construction can be done without it, since the interior of walls and ceilings is still accessible.
