Bluebottles

Cerocco

Ok I don’t know where to post this but I’m looking for help. I’ve a new kitchen. 6 month old. In the last 2 weeks I’m seeing up to 7 bluebottles in the kitchen. I kill them every day and yet more appear. I have been really careful in Relation to opening doors and windows and I’m convinced they are coming from inside the house but I just can’t find where. I did a deep clean when took down the Xmas decorations and totally sanitised the downstairs but yet they still appear. Does anyone have any ideas on how i can get rid of them?

Fly papers, they give the place a sort of old world charm.

Any chance these are cluster flies https://merlinenvironmental.co.uk/blog/pests/flies/lots-of-flies-in-the-house-suddenly-in-2022-heres-what-to-do-uk/.

Cluster flies are a nuisance, but while they are undesirable and unsightly and tedious to deal with, they don't, so far as I can see, go onto food or other surfaces where they are going to create health problems. Bluebottles are a bit bigger than cluster flies and have a kind of blueish metallic sheen to them.

If they are bluebottles you need to be taking extra care to keep food waste covered and disposed of, and bins clean. I think its much more likely they are cluster flies though, they tend to appear in batches, I usually spray them, close the door on the room then go in a while later and sweep or vacuum them up. The article quoted suggest leaving doors or windows open for them to escape, but it seems to me that is so many more flies to perpetuate the cycle.

Just occasionally, usually on a sudden warm day, I go to the garage, open the sliding door and a huge wave of flies comes straight at me as they attempt to escape, yuck!
