I have had a problem with these small brown bugs as, I will see one & I then may see another one another day & that is if I do not kill it... it is very small & it is brown & it flies & I have not yet been able to really see it close as, when I do notice it, I am trying to swat it & it moves real fast & it almost reminds me of a moth? But, really not too sure... I do not leave food out & keep my fruit in the refridge & when I open up something it goes in my fridge but, I do have cat food out & I have had cats for years & this is the first time I have noticed them... I have not had my windows open as, it has been too cold for me to do that... I was wondering if anybody has any idea as, to what they are or how to get rid of them completely?? Thanks

Do they look something like these?
