Rats and mice extermination

Rats and mice Control

Rodents can be found in our homes, supermarkets and restaurants. Most place like Warehouses and grain mills, are especially vulnerable to rodent infestation. By the way rats and mice will eat anything man or his livestock eats. They are active at night, yet rats are seldom seen during the day except when populations are exceedingly large. Rats and mice can crawl through very small crevices, which makes it hard to confine their movement. Even if you can’t see them, you may hear them moving after dark. If your pet paws at a wall or cabinet it may be after a lurking rodent. Cats and dogs are not much of a deterrent to rodents.

Signs of Rats and Mice infestation

  • Do you find rat droppings around dog or cat dishes?
  • Do you hear noises coming from the attic just after dusk?
  • Have you found remnants of rat nests when dismantling your firewood stack?
  • Does your dog or cat bring home dead rat carcasses?
  • Is there evidence rodents are feeding on fruit/nuts that are in or falling from the trees in your yard?
  • Do you see burrows among plants or damaged vegetables when working in the garden?
  • Do you see rats traveling along utility lines or on the tops of fences at dusk?
  • Have you found rat nests behind boxes or in drawers in the garage?
  • Are there smudge marks caused by the rats rubbing their fur against beams, rafters, pipes, and walls?
  • Do you see burrows beneath your compost pile or beneath the garbage can?
  • Are there rat or mouse droppings in yours’s recycle bins?

Rats and mice carry diseases

To sum up, Rats and Mice carry diseases and eat and contaminate our food. In addition, rodents co-exist with humans and closely associate with human habitats for food, water, and shelter. If living conditions for the rodents (food, water, and shelter), are right, they can multiply quickly. In your rodent control program, the essential first step is to eliminate or control their food, water and shelter provisions.

Damages: Rats and Mice can do.

Rats and mice extermination: Rats eat and contaminate foodstuffs and animal feed. They also damage containers and packaging materials in which foods and feed are stored. Both rat species cause problems by gnawing on electrical wires and wooden structures such as doors, ledges, corners, and wall material, and they tear up insulation in walls and ceilings for nesting. Norway rats can undermine building foundations and slabs with their burrowing activities and can gnaw on all types of materials, including soft metals such as copper and lead, as well as plastic and wood. If roof rats are living in the attic of a residence, they can cause considerable damage with their gnawing and nest-building activities. They also damage garden crops and ornamental plantings. . Plague is a disease that both roof and Norway rats can carry.

Difference between Rats and Mice

In brief Rats are larger than mice, with correspondingly larger heads and feet. In short rats also have coarser fur than mice. Mice are curious, while the rat is cautious. You will find Norway rats in burrows and the lower levels of a structure, while Roof rats prefer the upper levels of structures.

The brown rat is nocturnal and is a good swimmer, both on the surface and underwater, and has been observed climbing slim round metal poles several feet in order to reach garden bird feeders. Brown rats dig well, and often excavate extensive burrow systems.

1)Norway Rats

  • Norway rats eat a wide variety of foods but mostly prefer cereal grains, meats, fish, nuts, and some fruits. When searching for food and water.
  • Norway rats usually travel an area of about 100 to 150 feet in diameter; seldom do they travel any further than 300 feet from their burrows or nests.
  • The average female Norway rat has 4 to 6 litters per year and can successfully wean 20 or more offspring annually

2)Roof Rats

  • Like Norway rats, roof rats eat a wide variety of foods, but they prefer fruits, nuts, berries, slugs, and snails.
  • Roof rats are especially fond of avocados and citrus, and they often eat fruit that is still on the tree. When feeding on a mature orange, they make a small hole through which they completely remove the contents of the fruit, leaving only the hollowed-out rind hanging on the tree.
  • They’ll often eat the rind of a lemon, leaving the flesh of the sour fruit still hanging.
  • Their favorite habitats are attics, trees, and overgrown shrubbery or vines. Residential or industrial areas with mature landscaping provide good habitat as does riparian vegetation of riverbanks and streams. Roof rats prefer to nest in locations off the ground and rarely dig burrows for living quarters if off-the-ground sites exist.
  • They often can be seen at night running along overhead utility lines or fence tops.
  • They have an excellent sense of balance and use their long tails to steady themselves while traveling along overhead utility lines.
  • They move faster than Norway rats and are very agile climbers, which enables them to quickly escape predators.
  • They can live in trees or in attics and climb down to a food source. The average number of litters a female roof rat has per year depends on many factors, but generally it is 3 to 5 with 5 to 8 young in each litter.

3)House Mice

  • Size: 7 – 9.5cm in body length and its tail grows around the same length;
  • weigh between 12 – 30g;
  • Their relatively small feet & head and large eyes & ears distinguish them from a young brown rat (Rattus norvegicus).
  • Life Cycle, 4 – 16 young per litter, 7 – 8 litters a year;

4)Field Mice

  • Head and body size 80 – 100mm in length, Tail 70 – 90mm;
  • A male Field Mouse can weigh up to 25g, Female – up to 20g;
  • The fur colour on the head and back is like sandy/orange;
  • Yellowish fur on the flanks, white on the belly;
  • Usually has a small streak of yellow on the chest.
  • Average lifespan is two to three months;
  • Breeding seasons is from March to November

5)Deer Mouse

  • Deer Mouse (Peromyscus maniculatus), typical mouse with moderately long tail, large ears, prominent eyes and pointed nose well supplied with tactile hairs.
  • Upper parts are grey or brown, depending on age and subspecies; underside, white. Even the tail is 2-toned.
  • Deer mice are strongly nocturnal. In winter, the northern deer mouse (P. m. borealis) undergoes bouts of light torpor, lasting for up to several days, in which body temperature may fall several degrees, but it does not actually hibernate.
