Moths come in a wide variety of shapes, sizes, colors and body types. Moths that appear in houses are most likely a grey color or brown / red. Many moths feed on pollen while others can be a big problem for agriculture. Moths are known for eating clothing but they are also prey for birds, insects, spiders and even lizards.
Moths can be attracted to light and fly around it in a manic fashion. Moths fly through open doors and windows especially if lights are on inside.
Sprays are not an efficient way to remove this pest. Indoor infestation needs to be treated by identifying the moth and finding it's preferred breeding material so that further infestation is halted. For professional help contact NPCS for a free assessment and plan.
