As the weather cools one of the most common pests we are asked to manage is rodents, who seek warmth and shelter in your roof void or outbuildings.
Often you will be alerted to the presence due to hearing scratching noises in your roof void, staining marks on ceilings, or the unpleasant odour! Or lack of snails in your garden...
Identification is vital before any treatment can be carried out, and the easiest way is to inspect droppings which differ in size and shape depending on species.
"The Burrower" is brownish red in colour with small ears, blunt nose and stocky body. This rat burrows in close proximity to food and water sources preferring meat, fish and grains.
"The Climber" is dark grey with large ears, pointed nose and thin body. This rat nests in trees and roof voids in close proximity to food and water sources preferring fruits, vegetables, seeds and grains.
"The Scavenger " is black or dark grey with small head and body. This mouse can be found almost anywhere and will eat almost anything.
