Description

Moles live underground in fields, lawns, and meadows where their tunneling creates snakelike ridges on the surface. These tunnels usually kill grass, much to the frustration of homeowners. (pictured left) Moles feed on Earthworms and Grub Worms (85% of their diet) and insects. In search of food, they literally swim through the soil by digging with their short, outward-facing,spade-like front feet. Moles are six to seven inches long and weigh about 4 oz.

 

 

Characteristics

  • Moles prefer moist, sandy loam soils in lawns, gardens, pastures and woodlands. They generally avoid heavy, dry clay soils. They construct extensive underground passageways — shallow surface tunnels for spring, summer and fall use; deep, permanent tunnels for winter use. Their nest cavities are located underground, connecting with the deep tunnels.
  • They can eat 70 to 80 percent of their weight daily. They actively feed day and night at all times of the year.

 

Mole Activity

Mole activity in lawns or fields usually appears as ridges of upheaved soil. The ridges are created where the runways are constructed as the animals move about foraging for food. Burrowing activity occurs year-round but peaks during warm, wet months. Some of these tunnels are used as travel lanes and may be abandoned immediately after being dug. Mounds of soil called molehills (pictured below) may be brought to the surface of the ground as moles dig deep, permanent tunnels and nest cavities.

bioLawn’s Monthly Mole Control

Curative:

  • bioLawn offers our Monthly Mole Control Program for four to eight months throughout the season. (Depending on severity)
  • Worm baits are used which mimics a moles natural food source.
  • Baits are placed below the surface into active mole through a small hole that is then sealed. Moles will typically consume all the bait within 48-72 hours. The subterranean placement and quick consumption makes accidental contact by pets and children very unlikely.

Preventative:

  • bioLawn also uses an organic repellent that is applied to areas of mole activity to deter moles from entering your turf. This treatment is generally applied once the initial resident population is under control.
