As the weather turns wet and cold, rodents seek shelter in buildings. In Gibraltar, three species of commensal rodents are common.
Common Rodent Species in Gibraltar
House Mouse
The house mouse is small, measuring around 90mm in length. It is typically grey or brown, with a white or cream underside. Its body is pear-shaped, and its tail matches its body length. The droppings are rice-sized, spindle-shaped, and about 6mm long. They tend to be scattered as the mouse runs.
Black Rat
The black rat is medium-sized, reaching about 200mm in length. Its colour ranges from black to grey-brown, with a white underside. This rat has a slender body and a tail longer than its body. Its droppings are sausage-shaped, measuring around 15mm, and are also scattered as they move.
Brown Rat
The brown rat is slightly larger, measuring around 220mm in length. It is usually brown-grey with a lighter underside. This rat has a thick-set body and a tail shorter than its body. Its droppings are spindle-shaped, about 20mm long, and tend to be found in groups as they frequent specific toilet sites.
Preventing Rodent Infestations
To prevent rodent infestations, it’s essential to store food correctly. The house mouse consumes about 3g of food daily, which is roughly a tenth of its body weight. Sealing gaps and holes in buildings can prevent rodents from gaining entry. Using wire wool is effective, as rodents cannot gnaw through it. Remember, if a pencil can fit through a gap, a mouse can squeeze through it.
Signs of Rodent Activity
Identifying signs of rodent activity early can help mitigate damage. Here are some common indicators:
Sightings: Spotting the animal itself, along with droppings and damage, is a clear sign. The term "rodent" comes from the Latin word "Rodentia," meaning "continuously growing teeth." Rodents can cause significant damage by gnawing on various materials, including cables, wires, pipes, wood, mild steel, and even concrete.
Smear Marks: Rodents have greasy fur, which can leave grease marks along their frequently used pathways.
Odour: Both rats and mice emit a distinct smell. A trained pest control technician can identify this odour in enclosed spaces.
Effective Pest Control Solutions
If you suspect a rodent problem, it’s crucial to act quickly. Effective pest control solutions can help eliminate these unwanted guests. Professional services can assess the situation and provide tailored solutions.
