Bats in Buildings
Scotland is home to ten species of bat, and many of these choose to roost in buildings at least part of the time. Each species has its own preferences, from the habitats they frequent to the insects they hunt and the types of buildings and structures they like to use for roosting.
Assessing Your Property for Bats
When conducting a bat survey, we look for several key factors:
#1 Signs of existing bat roosts
From droppings to ‘smears’ or other marks at roost entrances, signs of a bat roost can be hard to spot. Many roosts, particularly those with a single bat, leave no external trace (more below). That’s why we will also look at…
#2 Potential roosting Spots
Different species have different preferences, so we will look for uneven roof tiles, cracks in masonry, and other features that could create space for a bat roost.
#3 Nearby Habitats
Each species has a different threshold for traveling to and from their foraging habitat. The likelihood your property has a bat roost (or roosts) depends on the types and distributions of woodlands, water features, meadows, and human features in the nearby landscape.
#4 Historical records
Biological records centres exist across the UK, and they hold the previous records of each species in a secure and accessible database. We will look at these databases to see what’s already known about the bats near your property.
Telltale Signs of Bat Presence
Wondering if you might have bats? Here are some clues to look out for:
Bat droppings: Often found below roost entrances or under roosting areas in the roof. These droppings are blackish, cylindrical, and slightly knobbly, measuring 6-12mm long and 1-3mm in diameter. Unlike mouse droppings, bat droppings crumble to powder when squashed.
Urine spots: Look for these on windows or other glass surfaces.
Greasy marks: Bats can leave smear marks at roost entrances.
Chittering sounds: Listen for these distinctive noises in the evening during warm weather or summer months.
Remember, bats are protected species, and it's crucial to consult with professionals before undertaking any work that might affect them.
