Not exactly a DIY question. But I have recently noticed a lot of flies in my house. They look like mostly horse flies (completely black in color).
I have used electric impulse swing racquet to kill few of them, but after i kill 4-5 and area looks clear I see another 4-5 in some time (around an hour or so). so far within last 30 hours I might have killed around 60 flies in multiple batches of 5-7 flies at a time.
It has been raining here in Santa Clara County, California from past couple of weeks and was wondering if it can be the reason. To add to it I had been away and my house was closed for close to 1.5 months but there was no trash/food which was in open.
I also noticed similar fly insects in a unit close by my place.
So am wondering if its a seasonal thing (seeing it for the first time here in last 4 years).
Also if someone can recommend how to get rid of them.
Thanks
