Cluster flies will enter our homes through even the smallest of cracks around door and window frames or through any tiny unsealed openings. You can always try and remove access to your property by using caulking to seal any gaps around door and window frames. It’s unlikely you will be able to stop all of them getting into your loft.
If you find a large infestation you are likely to need the help of The Exterminator Pest Control, we can use treatments such as residual sprays to target any active flies and others as they emerge from hibernation. It’s always best not to use home remedies as these will only treat the cluster flies you can see and in older properties Bats may be in residence. All bats in the UK are protected by the Wildlife and Countryside Act 1981 and it is illegal to use any type of insecticide that may come into contact with any bats.
