We get flies every summer. Every time someone opens the door, in comes a fly or two. I haven't found a way to get rid of them yet either. I usually just hand the 14 year old the fly swatter and tell her to get busy!
We never have an issue with flies, but this summer it is awful!!!!! I hung to fly papers that they are totally avoiding. Ours must be older flies because I was killing those slow things by swatting with a dish towel!!!
Ugggg we had fruit in the fruit bowl and had some bananas and the fruit flies/gnats/whatever showed up! They are driving me insane and I can't get rid of them. I have sprayed flying insect spray and it doesn't seem to bother them! Driving me crazy. No more fruit/bananas and I checked for a forgotten bag of potatoes. Nothing! I had been pouring bleach down the drain but ran out (that seemed to make them leave). I need to get more.
I will try bleach down the drain. I was doing vinegar, but will go heavy duty commando.
I stunned/killed upwards of 40 last night and had about as many this morning when I got up. I once had a cat that would hunt them down and eeat them (yuck) but this is the first year I have had more than 1 or 2. I actually opened my screen door to let some out and it helped a little.
but do you have a sink you rarely use?? It is possible they are hatching in the trap. That is where mine were coming from, nice hot water and a little drain cleaner and wala (sp) they were GONE! (along with most of my sanity )
Is it possible they are cluster flies? They look like house flies, but are a little larger and tend to move slower. I discovered the difference when I bought my house and had flies that were "driving me nuts". Fall and winter came and I thought they were gone until I started finding a few in January on the windows. I looked it up because we don't have flies in Maine in January, at least not outside.
If you have cluster flies they won't be attracted to a food source in your home so cleaning the drains won't help. I vacuumed them out of the windows because there were so many there. I also made sure my home was sealed so they didn't have easy entry back in in the fall. I haven't seen any, but the 2 cats I have now would take care of them quickly if I did have some so I may not know about it.
If nothing is working for you try googling it to see if you can get some relief.
get a small container and fill it with cider vinegar and put a drop or 2 of dishwashing soap in it. The gnats/flies are attracted to them and die. I empty it every few days and put more out.
It really works. If you don't want to kill them
get a cup, a a piece of fruit like a strawberry bite into it so the juice is out. Make a paper funnel to go into the cup. they get in there but can't get out. I recommend putting the cup insice a plastic bag and in the morning just pick up the bag, seal it and take it outside.
