Is there a relatively "safe" product to eliminate cluster flies ... without doing permanent damage to the human residents in the household. We've usually contented ourselves with window strips, but this year, we have hundreds and hundreds a day (without word of a lie!) Please help!

You might want to do a search on the web through a popular browser such as Google. One site you might want to check out is among others. I'm not exactly sure what "relatively safe" means, but it's probably better to use products and solutions that are entirely safe for your family, friends, pets and the environment. Good luck.

We have hundreds a day too, it must be a bad year for them. They were getting into our attic space and then from there I suppose coming into the house. Some products that can be sprayed are organic but not sure how effective they are. If you find anything that works, let me know too !!! Good luck.

Doktor Doom House & Garden Insecticied Spray is safe to you, your pets, friends etc. Apply it to your window sills and whatever other surfaces that they are congregating on.

One application will do it.

You must look at why you have cluster flies in the first place. They enter in the fall seeking warmth. First insulate and ventilate your attic. Making sure it is the same temperature as outside. The colour of your roof also helps - go with light colours - not Dark!

Finding the reason is always the best way before treating the sympton. If only our health system worked this way. Good luck.

Hi! I just joined this site and happened upon this post. I too have a problem with cluster flies. There is a non-toxic canadian invention called 'The Cluster Buster' out there. The flies are trapped in a powdered egg shell type of material inside a trap. There is no noise, no mess and nothing for you to handle or see. Best of all one trap holds loads of flies so you only need to replace them every 6 months or so. You should check out this guys website at (i am not connected to this website or this business either, just someone who has tried and really liked this product)

thanks for your time, Jennifer
