Hello, We've seen these flying insects in our home off and on for about a month or so. The most at one time was 5 of them in a half bath. Usually it is just an odd one here and there. One buzzed by me and sounded like a mosquito. These are quite a bit larger than the normal mosquitoes we see in the yard. Best guess, close to ½". They've been seen in bathrooms, kitchen, living room, bedrooms. No known standing water source. No indoor pots with water trays, etc. Any idea what they are and whether or not they could be breeding indoors or just sneaking in from somewhere. Pics are from a kitchen faucet. Thanks!
