I consider myself "somewhat" an expert on mole eradication, short and long term eradication, as evidenced by over 60 kills in 2 seasons. The old house I bought had its yard infested with moles. I'm a grass guy and they were destroying everything I did to make my lawn nice. My first course of action was for long term. GRUBEX. Just have to get rid of their Filet Mignons. No other way around it. NOW, for short term and to go directly into mole warfare I battled them in a 2 front attack. Bought the best trap on the market IMO called the Moleliminator. It's like a double knife bladed deal with massive springs which must be set with your body weight. You've got to be able to learn their trenching and travel habits to set these in the right spots. I can get in to this aspect if anybody needs more info. Once these are tripped, there's no survival. This trap is bad to the bone. 45-50 of my kills were on this trap. Procedure #2. Get up at the crack of dawn, and go to the garage and secure your best spade. Hopefully in the previous days you have done your homework and know what part of the yard or even what trench may be HOT in the morning. They move and eat in the morning. They move and eat in the late evening as well. The next thing is slowly walking out to a HOT trench and WAIT. Sometimes it's immediate. Sometimes it takes 15-20 minutes to see movement. Used to love the look of my neighbors early in the morning when they were going to work and there I stood motionless out in my yard with a shovel. They were probably checking the obituaries the next day. lol. When you do see movement, trace the trench and figure about where he is gonna be, slowly place the tip of the spade in line with the trench, jump up as high as you can jump and come down on the spade with your feet. Try not to be drinking during this stage.lol. In one swift motion, pluck out the biggest piece of dirt that you can muster and THERE HE IS. Chop his fury butt before he tries to burrow back in. This 3 pronged approach took my yard from being a disaster with trenches and volcanoes to where I had NO moles in 3-4 years. The 2 years after the big year where I hit 60, were just stragglers. Had maybe 2 one year, 1 the next and then they were TOTALLY eradicated. My trap has gotten no use in about 5 years now. It paid for itself.
