Mysterious holes in the garden!

Very often one finds holes in the home garden, lawns, grounds, farms, and one does wonders how these holes appear overnight. It’s just a, not a big deal to dig those holes for the guests who peep into our territories.

These mysterious creatures start owning their home in one’s gardens and lawns. They litter the area and cause menace.
Who are these trespassers?

How do they make holes in our territories?

Let’s know about these trespassers.

The culprits include rodents such as rats, mice, voles, pocket gophers, ground squirrels etc.

One of the two species of rats that live near people is a burrower. Norway rats like to live at ground level or underground, so they commonly dig holes.

The rat digs a hole that’s generally 2 to 4 inches wide, less than 18 inches deep and up to 36 inches long. It makes other holes at ground level for emergency exits. A dominant male, his female and their young and low-ranking males share the burrow, which has a nest at the center. Unlike a mole’s digging, the rat digs deep enough underground that there’s no raised soil showing at the surface. They are usually close to the water but are also found in a variety of other habitats such as hedgerows, rubbish tips and often under covers such as tree roots and logs. Rat holes generally have a fan-shaped mass of freshly dug soil outside and the holes are connected by well-trodden runways.

Mice can dig extensive burrow systems, often under tree roots. Wood mice dig burrows in cereal fields and similar open situations. The tunnels are generally only a few centimeters below ground, with entrance holes about 3 cm in diameter. Mouse holes are often camouflaged or blocked with debris, such as small stones, clods of earth or twigs. Tunnels frequently connect to runways above ground through dense vegetation.

Voles often eat succulent root systems and burrow under plants or ground cover and eat away until the plant is dead. Bulbs in the ground are another favorite target for voles; their excellent burrowing and tunneling skills give them access to sensitive areas without clear or early warning.

Pocket gophers, commonly referred to as gophers, are burrowing rodents of the family -Geomyidae. They are commonly known for their extensive tunneling activities. All pocket gophers create a network of tunnel systems that provide protection and a means of collecting food. Their burrows can be found in many areas where the soil is softer and easily tunneled. They often appear in vegetable gardens, lawns, or farms, as gophers like moist soil. The burrow system can cover an area of 200 to 2,000 square feet with the main runway situated parallel to the surface and about 6 to 18 inches below. Nesting and food storage areas will be located as deep as 6 feet.  Tunnel systems that cover a larger area are usually found in areas with dry landscaping in order to be near an adequate amount of food resources. The infrastructure can continually be changing as gophers seal off areas or dig new pathways as needed for food or mating. Underground water lines or sprinkler systems can be damaged by the incisor teeth of a gopher as they create burrows. Trees can also be damaged during the burrowing process from root pruning or clipping.

The ground squirrels are members of the squirrel family of rodents – Sciuridae, which generally live on or in the ground, rather than trees. Like their name implies, ground squirrels burrow into the ground, creating massive hideouts 15 to 20 feet long. These tunnels and dens typically have more than one entrance, which is small, two-inch- diameter holes. It is relatively easy to identify ground squirrel holes in the yard, as they are distinct from those of other burrowing pests. These holes are typically clean and devoid of excavated soil, with the surrounding grass worn from continued use. As with other burrowing animals, ground squirrel holes in yards, gardens, pastures, and crop fields can quickly become a problem. Due to the very nature and size of the tunnels themselves, the ground above can collapse over time. Additionally, these holes easily become tripping hazards. Burrows around ornamental trees and other plantings can expedite the drying out of root systems. Finally, ground squirrel holes under structures can erode away the soil, causing issues with foundations.

These trespassers need to be prosecuted!

How can it be done?

C Tech Corporation has a solution for this menace. CombirepelTM, a rodent aversive produced by C Tech Corporation is an extremely low at toxicity, non-carcinogenic and non-mutagenic compound, non-hazardous, non-dangerous and environmentally safe rodent repellent.

Our product is available in the form of a masterbatch, which can be directly incorporated while manufacturing an application. The polymeric pipes, seats, playing equipment, cables, etc used in the gardens can be incorporated with our masterbatch.

The product available in the liquid concentrate can be mixed with paints and applied on the concrete areas from the gardens. The concrete fences around the gardens can be coated using this product.

Also, it is available in form of top coating namely lacquer that can be directly applied as a top coat on the surface of wooden/concrete/metal fences.  The product is compatible with most of the surfaces like metal, concrete, polymer, ceramic, wood etc.

The product triggers a fear response in rodents thus protecting the application. It causes severe temporary distress to the mucous membrane of the rodents due to which the pest stays away from the application. The product triggers an unpleasant reaction in case if the pest tries to gnaw away the application. After encountering the above-mentioned emotions, the animal instinctively perceives it with something it should stay away from and stores this information for future reference. The fact that certain rodents are repelled is mimicked by other rodents as well. Thus, the other rodents too stay away from the applications. The unpleasant experience is imprinted within the animal’s memory and passed on to its progeny.

Thus, CombirepelTMactually helps in modifying rodent behavior. Hence the spread of diseases caused by rodents can be eliminated.
