Cluster Fly Killing PowdersCluster flies are normally a problem in March - April when they become more active after over wintering in a property and again in September - October when they access properties trying to find somewhere to over winter.
Cluster flies leave a scent trail to their *winter hideouts* and so the aim has to be to kill as many as possible to lessen this *trail* and lessen the amount of cluster flies that are finding your home or business a good place to over winter.
Our Cluster Fly Killing Powders include an insecticidal powder in a handy 150g puffer pack and an organic powder that is available in a 450g *shaker* pack or a 2kg tub. These powders are ideal for use around the edges / joints of where the floor meets the wall, in any affected area, which is where cluster flies may be living and hiding. These powders are also ideal for use in any crack, crevice or gap where cluster flies may be overwintering.
If you need to get the killer powder deep into holes, nooks or crannies, we stock a Cluster Fly Killing Powder Dust Blower.
