My 5 year old home has raised construction on blocks approximately 3 feet off the ground - a common construction type in New Orlans. Last winter, my first winter in the house, I noticed that the floors are very cold, especially aound where water pipes enter the house. There is no insulation of any time under the house & the opening is open. Before I start calling contractors for estimates, I'm trying to gather some information about what would be the best type of insulation. I'm not sure about batt type insulation, since it seems to be a convenient nesting place for rodents. Would a blow-in type insulation be better? Or something else.

Your best bet is sprayed-on foam insulation. They can spray it right onto the bottom of the floor, and fill the gaps around pipes, etc. It expands, turns very hard when dry, and mice must really hate it. They wear down their teeth just trying to get through it. :-)

I agree. batt insulation will sag over time. It get compressed around wiring, plumbing and ductwork. Spray will will cost almost twice as much but will worth in in comfort and utilty cost.
