Mole Poison

What you should know about Mole Poison

Although these creatures moving in have little real danger for the yard, most homeowners turn to tactics such as mole poison to get rid of the creatures.  The effectiveness of this method for eliminating moles is debatable; homeowners should become familiar with all possible options before deciding which method to utilize.


A small mammal measuring only about 8” in length, the mole can be found in almost every region of the world except Australia and the northern tip of South America.  It lives underground where it can be in close proximity to its main food source, earthworms.  The animal possesses powerful forearms that are equipped with front facing paws and sharp claws that enable them to tunnel through the earth in search of their prey.

The preferred habitat of the mole is wet or moist soil, which coincidentally is also the natural home of earthworms.  During a wet period of the year, the worms exist just under the surface of the earth; during the heat of the summer as the soil dries out, the worms delve deeper toward more cool and moist territory.  Moles follow the lead of the earthworm.  Long, winding tunnels that heap earth upward in hills is evidence that moles are hunting for the earthworms near the surface of the soil; tunnels deep beneath the surface are rarely even known to exist by the landowner.

Eating takes up a great deal of the mole’s time; day and night finds the insectivore digging and searching for food.  Because of this near constant activity, a mole can prove to be quite a challenge to a well manicured lawn; leading most homeowners to seek a means of eliminating them to preserve their landscaping.

Mole control

Tunnels dug by moles are not only unsightly, but can prove to be a hazard as well if an individual were to unwittingly sink into it while walking across the lawn.   Several methods of getting rid of moles have been attempted over the years, ranging from traps to poisons.  Many individuals believe trapping to be the most effective means of controlling the animal; scissor traps, harpoon traps are designed to crush or pierce the animal as they attempt to clear a blocked tunnel.  There are also several ultrasonic devices that have been created that are thought to repel the mammal through high pitched sounds, and special windmills that cause vibrations in the soil that make the mole leave the area.

An alternative to trapping the mammal is to use mole poison.  Poison is commercially available in a few different forms; coated peanuts and coated gummy like worms are the most common forms.  While the poison itself could likely be extremely effective in killing the mammal, getting the mole to eat the coated items can be the problem.   While it is true that a mole’s eyesight is pitifully lacking, the sensitivity of the nose is keen.  The animal is adept at locating and identifying food through receptors in the nose simply by touch.  This means that the mole is not easily fooled into ingesting foods that simply resemble their favored meal.  Grains or peanut poisons are virtually ignored by the mole, as this creature is solely an insectivore and not attracted by other food forms. Should the poisoned food actually be eaten, a bigger problem could plague the homeowner; enduring the lingering odor of the decaying corpse of a dead mole.



It is possible to make a yard less desirable for the inhabitance of a mole by simply avoiding a wet yard that is conducive to the lifestyle of the earthworm.  No earthworms mean there will not be a mole problem.   Treat your yard regularly against grubs, which are another type of food that moles seek.

Moles are not considered to be a dangerous animal and cause no harm to the yard itself besides creating tunnels; however, most homeowners seek to rid their yard of the creatures through mole traps or mole poison.  Learning more about the different methods available can help to educate the homeowner and assist them in choosing the best option for them.
