@UrbanGardener is right about placement! I use flour dusting to track their routes before setting traps. Increased my catch rate by 300%.
Surprisingly, the dollar store traps worked just as well as name brands for me. Just need to adjust the sensitivity yourself.
Warning about electric traps - keep away from kids/pets. My neighbor’s dog got zapped (was okay but scared us all. Now I only use enclosed snap traps.
