Have you seen cluster flies congregating around your home or sheds already this season? Let me know by replying below.
They are named cluster flies because of their habit of congregating in large groups or swarms in dark places such as attics, corners of dark rooms, 'nooks and crannies' and 'cracks and crevices'. Each fly releases a pheromone (smell) that attracts others. This pheromone will linger on even after all the flies have been destroyed and removed and thus will continue to attract cluster flies to that area so that the clusters keep recurring. It is therefore important that treatments are continued even when there are no flies present.
How to get rid of Cluster Flies and keep them away
Kill the adults to prevent them laying eggs in surrounding grass. Kill the larvae in the grass to prevent the adults clustering in your buildings.
If possible it is best to prevent the problem of these flies moving into your home by treating the larvae in the soil before they become adult flies. Use Lawngard Prills which is a slow release insecticide for removing pest insects from the soil. This is an ideal product to protect you from Cluster flies. Sprinkle these prills on grassy areas within 100-200m of your home.
When cluster flies are seen around a building on the outside, this is usually in the late summer and autumn, this final adult stage before clustering inside can be controlled with NO Flies Bait placed in strategic places around the exterior.
If you have the adult flies swarming and clustering in the house or other building you need to carry out a program of treatment.
Check around your house/buildings for clusters of flies in warm, dark, dry corners specially your roof void and eaves. If these can be accessed, spray the clusters with NO Bugs Super. If the clusters cannot be found or accessed use NO Bugs Bug Bombs or NO Bugs Borafume fumigators in the voids.
Once the flies in the cluster are dead, clear away as many bodies as can be reached. If you use a vacuum cleaner ensure the bag is disposed of immediately. Spray the surfaces they were clustering on with more NO Bugs Super to prevent new clusters forming where the pheromone lingers.
Treat the surfaces around the home where flies have been seen and entry points to the roof void around the eaves etc. with NO Bugs Super.
Treat again prior to the next season to prevent new clusters collecting. Given a chance they will use the same areas to form clusters.
Why do flies follow garbage trucks? Because they like fast food.
