Instructions
Look for a feathered, winged insect that looks like a cockroach.
Check out the wings. The meal moth's wings are folded back; the outer 1/3 of the wing appears reddish brown colored at the wing tips, while the inner 2/3 of the wing is light gray to yellow.
Size up the insect. The meal moth can be up to 5/8-inch long.
Determine the color of the wings. The meal moth resembles the fabric moth except for the wing coloring.
