The mole sheds about 5 kg of soil a day and as much as 1 ton a year
The mole is often called the “little temptation” because it persistently drills corridors below the ground despite various attempts by people to drive moles out of the garden. Moles are on the so-called Red List of Endangered Animals, so it is even harder for owners of gardens, lawns and greenhouses to drive moles out of the yard. Moles are very useful animals because they eat about 10 kilograms of larvae of harmful insects a year and thus reduce their number in the soil. The mole especially loves earthworms and does not forgive its own species if it strays into its molehill. Exceptions are individuals of the opposite sex during the mating season, which lasts from March to May. Moles also digging underground tunnels contribute to better ventilation and mixing of the soil. However, they are undesirable because with activities they disrupt the appearance of the yard, garden or other green areas, but also damage the root of the plant. Experts say moles can dig up to 2,000 square meters of moles. One should know that moles do not feed on plants.
The mole is slow but also elusive
The mole weighs 60 to 120 grams and is barely 15 cm long. The mole is not able to escape when it is on the surface of the ground because it has legs set sideways (due to easier movement through underground tunnels). The mole is difficult to catch because it rarely comes to light. She is not afraid of water and is a good scuba diver and swimmer and rarely leaves underground tunnels. In some states, they use traps to catch moles, which they then transfer to other habitats. This activity is expensive due to the effort to keep these useful animals alive, because due to the intensive metabolism, they eat almost twice their own weight per day. They must not be without food for more than 6 hours because otherwise they die. It is interesting that European moles find it easier to survive unfavorable conditions towards American moles (because European moles prepare reserves of live worms in their own warehouses). Moles do not need water by feeding on worms otherwise they need to find a source.
4 ways to drive moles out of the yard
- There is a new generation of repellents on the market (a means of repelling moles) in the form of a powder made from the urine of a predator (weasel, marten, lynx) whose smell the moles are afraid of and forces them to leave the territory.
- One way is to grow a castor plant that repels moles.
- Sealing moles with cloths soaked in oil, thinner or similar liquid with a strong and unpleasant odor. All means force the moles to flee but return to the tunnels as soon as the tunnels are ventilated.
- There are Ultrasonic electronic probes in the form of probes. These probes are buried just below the surface of the soil. They vibrate at certain intervals at a frequency of 300 to 400 Hertz (which is not registered by the human ear). Moles are irritated by this vibration. Moles have a developed lumen but vibrations feel the entire surface of the skin sensitive to various stimuli. Moles have the highest number of sensory cells per unit area compared to other mammals. Under optimal conditions, the UV device covers an area of 1000 square meters. The efficiency of this device depends on the substrate – vibrations are better transmitted through hard surfaces than humus. The probe should be buried to a hard surface if the humus layer is shallow. An additional problem is obstacles (walls, pipes, fences, pits full of sand and slag, etc.). in these cases, one should count on a smaller radius of operation of the device or possibly the installation of more probes. The sound can sometimes be blocked by a strong source or other vibrations (say vibrations due to traffic) that do not bother moles because they are used to these vibrations. UV diffuser has limitations. In large areas under crops where intensive tillage is required, a large number of probes are required. Therefore, it is most often used in backyards, small yards or greenhouses. Battery power lasts 6 months and the place where the device is buried should be marked to make it easier to find later.
