Yes, but they are not as prolific as Clothes Moths. If the infestation is as bad as you say, and it is clothes moth you would probably only have nylon clothes left by now.
if it is Meal moths, empty and disinfect/bleach all of your food storage cupboards, especially ones in which you keep rice...
Okay - the way to tell is that a meal moth has a very definite change in colour about half way down it's wings (see first pic)whilst a clothes moth does not. (see below)
