Mole Extermination - A Brief Survey Of Various Methods


This is a summary of some of the techniques used in mole extermination by consumers. In many homes across North America, moles are a major nuisance, with frequent damage to land areas under cultivation caused by their tunnels. In certain instances, moles weaken foundations, cause patios to be uneven and crack, and even destroy in-ground swimming pools.


Many homeowners also reported damage to plants themselves, believing that moles may have consumed parts of the plant itself, although this is more likely auxiliary damage. Moles primarily eat earthworms and the damage to plants is usually limited to incidental shearing and uprooting or hollowing out the dirt around the plant roots, causing them to die. Because of this damage, effective mole extermination is a key consideration.


There are seven different mole species found in North America. They are hardy mammals with excellent senses of smell and very limited sight. All species of moles have prominent front paws used for digging tunnels quickly, often in search of nutrient-rich earthworms. Moles also have very little in the way of eyesight, with almost no ability to detect more than changes of light.


According to the findings of Dr. Val Schaefer, moles have also been observed functioning in extremely high levels of CO2, with levels from 10 to 100 times the atmospheric level. Because of these adaptations, mole extermination, rather than repulsion, is often employed frequently.


Repulsion methods differ from mole extermination in that they attempt to make the environment for the mole unpleasant to the extent that the mole leaves. Such methods often require constant application in order to achieve the desired effect. Ultrasonic or vibration methods are intended to reproduce the presence of another mole with the presumption that moles’ territorial behavior will lead them to vacate. However, with the lack of an actual physical threat, moles frequently expunge the device from the soil and simply reclaim their tunnels.


Mole repellents are also used as an alternative to mole extermination with mixed results. Castor oil is one commonly-used method, coating the grubs and worms that the worms seek out as their primary source of food. The castor oil lends their prey a distinctly unpleasant taste and smell, thus causing them to seek new territory and leave the affected area. This method must be repeated multiple times a year in order to be effective.


Mole extermination is widely believed to be the most effective way of clearing a given area of moles. While there are many methods, some are more humane and more effective than others. Poisons are largely not utilized by consumers because they are difficult to obtain without a proper license. Mole extermination using poisons involves poisoning the prey of the mole and can have a large effect on the local ecosystem.


With regard to mole extermination, it a trapping method was seen to be the most effective and humane, with minimal environmental impact. A simple sub-surface trap that utilizes a trigger-claw setup to quickly eliminate the mole was the optimal method found, as shown in the Mole Pro trap.


The mole was caught within 3-5 days without exposing other large mammals such as pets to danger. Although some traps used non-etermination methods, these were ultimately judged to be inhumane because they often resulted in suffocation after the mole was trapped.




Overall, the mole extermination method exemplified by the Mole Pro traps was seen to be the most efficient method of mole elimination. These traps were favored for their simplicity, effectiveness, and safe methods of operation. Mole Pro traps were also judged the most humane for their quick and efficient jaw style trapping construction.
