Flies

[Beepy]

We are suddenly over run with small flies - 100's of them! Can anyone suggest why?

DO you have fruit bins/ compost bins..... we currently do to atm. the weather has clearly changed and gotten a lot milder overr the last week...they are all over our waste fruit bins

Any rotting vegetation or fruit around? or are you near any pools of stagnant water?

We had that last year in the shed.

Our pest control guy said it was Cluster flies.
Usually a sudden change in weather brings them out of hibernation, they will appear twice a year.
He fumigated the area, but said the pheromones left behind might attract them next season.

I have found it is often fruit, even find that in the girls wc as they discard food in the sanitary bins.

A few years ago, My Daughter was a Resident Artist in a school located in very large grounds, she lived in a room at the very top of the building, every now and again, her room would be inundated by these `Cluster Flies` they would be coming out of the light, light fittings and every little nook and cranny, not a very nice experience to get back to after a weekend home and return to that, only stayed there for a year.
Apparently, they hatch in the grass when the weather is right and go to the highest point.

We have no fruit, ponds or rotting veg. They are gross!
