Cluster flies are a real problem for some

Hello, loyal readers, it’s me again.
It will soon be coming up to that time of year again where cluster flies are causing a nuisance.
To the untrained eye, these can look like regular flies but there is a big difference. These are probably one of the biggest fly pests we deal with especially in the spring and autumn. You may start noticing flies gathering on one side of your property on the walls outside and on the windows both inside and out and generally on a south facing area as to get as much heat as possible while they can. These flies will start in small numbers but get worse over a short amount of time, and it can be perceived as the same flies there day after day but this is not the case. The first flies have arrived and are leaving an invisible pheromone trail for others of the species can follow. They have found a good site in which they can over winter ready next year. When the weather has become nice, and warm enough for them to fly off and go about their business you may start noticing fly issues this happens in the spring time as the weather is warming up as I’ve said. In the autumn this happens in reverse, as the weather cools the adult flies are looking for a place to overwinter in a temperature stable and safe environment. What does this mean to you as a home owner if you notice this? What it means is if you are experiencing high levels of flies in the spring or autumn the flies are either emerging from their winter escape (your home) or making your home their new residence for the winter. The pheromone trails they leave will help other flies know it’s a safe place to over winter the next year and this is a snowball effect. The more and more pheromones left previously, the stronger the draw for the next years overwintering cluster flies.
Where do we usually find cluster flies in numbers? In general cluster, flies are normally found in the voids of your house. The biggest voids that are accessible are the loft and occasionally a basement. An area that is generally dark, and doesn’t fluctuate in temperature as much as being exposed to the elements outside.
Signs you may have cluster flies.
This can be different for many people, some notice large numbers of flies in the windows or on the walls, others may hear buzzing like wasps in the loft (September-November time) when trying to sleep. Some people find out when entering the loft with a head lamp on or switching a loft light on whilst planning ahead and finding out all the Christmas decorations for the coming festivities only to be met with a cloud of flies or removing a loft hatch and a lot of fly bodies falling on them. This isn’t nice even for us and it can still give us a shock when it happens to us, we are only human at the end of the day.
We can treat this very easily using a range of professional use products and we are currently also trying to use as many organic products as possible in all our treatments be it insect or rodent. Either way, we will have a solution to suit your needs.
When we say, if you have a pest we have the solution! We really do mean that. Anyway, that’s a blog on its own. So, for now, I will say farewell and wish you all a pest free environment wherever you are.
