The Victor Easy Set Professional Rat Traps are the standard in rodent control. With an original wooden snap trap design and an improved larger trip pedal to ensure higher catch rates, this trap will help you to effectively eliminate rodents around your household or business. There are (2) settings, Firm and Sensitive, these settings allow you to control the sensitivity of the trap. In addition, these traps require no chemicals or poisons although we do recommend using a bait or lure. For best results, these rat traps should be placed where rodents travel, such as along walls at 2 to 3 ft intervals. See our instructional video on rat and mouse trapping!
