Use BOTH the small and large ends of the Dominator Call® for making the Raccoon call sound. To attract Raccoons, bite down on the small end of the call and close it off about halfway. Blow and start trilling (trilling is the rapid vibration of the tip of your tongue behind the upper teeth and roof of your mouth). This is an aggressive chattering sound made by a young subordinate Raccoon. Now flip the Dominator Call® over to the large end and repeat the trilling. This will produce the aggressive chattering sound made by adult Raccoons. This sound is lower in tone than the young Raccoon. Alternate between the young and adult Raccoon, repeating these sounds 5 to 8 times from your setup every minute or two. Repeat it. These call sounds will attract Raccoons to you. Remember, you are mimicking the sound of two Raccoons squabbling over a food source.
