Mole evidence of intrusion should be easy to recognize despite the fact that there are only a few types. Because moles spend the majority of their time underground, visual sightings are rare. Due to this the ways to determine if moles are intruding onto your property, and perhaps the cause of some problems in your landscaping are abstract. Read through the following techniques to help you recognize these types of evidence of intrusion.
Mole Evidence of Intrusion-Molehills
Evidence of mole intrusion could lie in small mounds of dirt found in your yard and gardens. Hills are formed when moles push dirt from their tunnel making out to the surface; out of their way and into yours! Look for mounds that are chunky and a have an underground line connecting them. Molehills vary slightly depending on species.
In the eastern portions of North America molehills can be anywhere from six (6) to 24 inches in diameter and from two (2) to eight (8) inches high. In the west the hills are normally slightly smaller in height and diameter.
Keep in mind that Shrew Moles do not make molehills and this method to determine if an American Shrew Mole is invading your landscaping may not work.
Mole Evidence of Intrusion-Tracks
Because the mole spends most of their time underground coming across mole tracks will be rare but not totally out of the question. Look for tracks in soft, wet soils or snow covered ground. Mole tracks will be faint such as the Eastern Mole track illustrated below.
Mole Evidence of Intrusion-Tunnels
All species of moles in North America will tunnel close to the soil surface when feeding. These tunnels will appear above ground and provide evidence of mole intrusion number one! Look for tunnels that are arched, enclosed and able to be flattened with your foot. They are normally found along sewer drain fields and shaded fencerows where insects and earthworms are more prevalent.
Moles spend the majority of their time in their underground homes patrolling the tunnels for food. This can make determining if you have a mole problem very difficult. The techniques above have been gathered to assist you in discovering mole evidence of intrusion.
