It is a myth that rat bait placed in your attic will make the rodents thirsty and therefore leave to look for water or dehydrate them so they don't smell. The truth is they will eat the bait, get sick and die in your home!
If you get sick, where do you go? Usually back to bed, and if a rodent gets sick they go back to bed too, which is in your attic or walls!
Over the counter rodenticides usually require multiple feedings to work. If rats or mice eat the bait and do not ingest enough poison it could just make them sick and therefore they start to avoid the baits. Placing baits inside a home or business can cause rodents to become sick or die inside the attic or walls and then once they start to decay, the odor can sometimes shut a business down or cause the homeowner to seek shelter else where for a few weeks.
Rats can crawl through openings of a 1/2 inch and climb vertical pipes of up to 3 inches in diameter. They can jump up to 3 feet from a flat surface and fall 50 feet without being injured.

They will chew on electrical wires, plastics, wooden furniture or any other hard surface to wear down their incisors. Chewed and exposed electrical wires are a cause of many house fires.
