...In the area I am in they call that poison....3 steps....thats all they get after a dose.....
Tres Pasitos:
This product is usually imported illegally from the Dominican Republic, Mexico and other Latin American countries. The name means "three little steps" in Spanish. The name implies that the product is so poisonous, mice will die very quickly after eating the poison. The active ingredient in Tres Pasitos is aldicarb. The EPA considers aldicarb to be a very toxic chemical that should never be used in your home.
Children and pets are especially vulnerable to poisoning by Tres Pasitos. The product is made of small brown grains that look like food. Tres Pasitos is often sold in sandwich bags with little or no labeling. Touching, breathing or swallowing even a small amount of Tres Pasitos can cause vomiting, weakness, dizziness, sweating, and shortness of breath. If you suspect someone was exposed to Tres Pasitos, call the Poison Control Center immediately at 1-800-222-1222 for medical advice.

Aldicarb is a fast-acting cholinesterase inhibitor, causing rapid accumulation of acetylcholine at the synaptic cleft. It is widely used to study cholinergic neurotransmission in simple systems such as the nematode C. elegans.
Exposure to high amounts of aldicarb can cause weakness, blurred vision, headache, nausea, tearing, sweating, and tremors in humans. High doses can be fatal to humans because it can paralyze the respiratory system.
In South Africa (where Aldicarb is popularly known as Two Step) it is widely used by burglars to poison dogs.
