Pest activity in the loft is usually indicated by noises reported by the occupant at quiet times such as during the night, when noises in the loft seem most noticeable. Noises in the night in a loft are surprisingly accentuated by the quietness of night, with the footfall of a mouse sounding like a squirrel having a party with his mates! Noises are also frequently encountered in the cavity walls, which is generally how rodent pests gain access to your loft. The initial access to the cavity walls is typically through broken air bricks, and in drier summers, through cracks in the lawn which lead to the foundations of the home and wall cavities thereafter. Rodents are very much three dimensional in their habits, so evidence of rodents in one location may have the source in another location within the property.
Rodents are the most common causes of noises in the loft. How to identify rat or mouse activity in the home? The house mouse (Mus domesticus) and the brown rat (Rattus norvegicus) leave different signs of their presence.
Rat droppings are larger, around 8mm. Rats typically use a frequent ‘toilet’ area, leaving droppings in specific areas. They also require a drinking location. Mouse droppings are smaller, resembling small black grains of rice, and do not generally require a drinking location providing there is some moisture in the food they eat. Droppings and urine locations are generally spread throughout their habitat as they are incontinent.
As well as gaining access from wall cavities, rodents can frequently travel between neighbouring properties along pipe and electrical cable runs. This can make eradication problematic in areas of multiple occupancy, such as flats, neighbouring houses and shopping centres.
Noises in the loft are not necessarily restricted to rodents being the cause. Another consideration regarding noises in the loft is squirrels (Sciurus carolinensis). At Pegasus, we get many call out requests for squirrels, ranging from agricultural issues to domestic loft issues. Squirrels are very good climbers and can gain access to roof tops by jumping from tree branches.
The use of fluorescent tracking powder can indicate which mammalian pest is causing the noises and can also indicate where the pest is entering.
Noises in the loft are sometimes caused by the activity of wasps or bees as they go about their business of visiting the nest in a loft in order to deliver food to the developing grubs, expand the nest size and generally advance their place in the world.
Another symptom of a nest in the loft is a wet patch developing in the ceiling below where the nest is located, as condensation from the nest activity permeates through. This generally occurs later in the season (August to November) as the nest reaches optimal size.
