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.

If you have questions about a potentially illegal or counterfeit product, or any pesticide-related topic, please call NPIC at 800-858-7378 (8:00am - 12:00pm PST), or email at npic@ace.orst.edu.
