OK, folks, let's all read the question:

I turn off the main valve of the water supply of my house
but some tell me to add antifreeze in sinks and toilets to prevent roaches from coming up the pipes if the pipes dry up. Is this a good idea?
So this raises four questions:
1. Do you have roaches in your drain waste pipes?
2. Will you be gone long enough for the P-traps to dry out?
3. Does antifreeze have a slower evaporation rate than water?
4. Will antifreeze (or water) prevent migration of roaches (#1) through the p-trap?
