i am doing a project where you use a plastic container and put insulation in it to keep a fake bug frozen in a ice cube from melting. It will lie under a lamp that is on. What are very good insulators that wont let the heat come in and wont let the cold get out?
Regular potting soil mixed with sand or just damp sand is fine. Her instinct is to bury the eggs and the sand or sand/soil mix will hold the shape better for that then the vermiculite. Vermiculite is better for incubating eggs.
Perlite works too, and you can find both vermiculite and perlite in a garden center or even at a Home Depot or Lowes. Walmart even carries them. If you're sure that she has never been with a male there is no point incubating the eggs. They will not hatch and it doesn't matter what she lays them in.
