Identify the Type of "Worms"
- Pantry Moth Larvae (Indian Meal Moth Larvae): These larvae are small, about 1/2 inch long, and creamy-white with a brown head. They often appear near stored food products.
- Grain Beetle Larvae: These larvae are also small, white or yellowish, and can be found in dry food items like flour, cereal, and pasta.
- Fruit Fly Larvae: Tiny, white, and often found in overripe or decaying fruits and vegetables.
- Maggots: Maggots are the larvae of flies and are often found in decaying organic matter, including garbage. They are typically white and legless.
Check for Physical Evidence
- Pantry Moth Larvae:
- Webbing and Silken Tunnels: Look for silky webbing and tunnels in food packaging, especially in grains, nuts, and cereals.
- Cocoons: Small, web-like cocoons may be found in corners of pantry shelves or food containers.
- Grain Beetle Larvae:
- Damaged Food Packages: Look for small holes or tears in packaging and fine powdery residue from infested products.
- Live Larvae: You may see small larvae in flour, grains, or cereal.
- Fruit Fly Larvae:
- Presence of Overripe Fruit: Larvae may be found in or near fruit that is overripe or decaying.
- Moist Organic Matter: Check for larvae in moist areas, such as garbage disposals, sink drains, or compost bins.
- Maggots:
- Garbage: Larvae will emerge from trash cans that are in need of the waste to be removed.
- Dead/Decaying Animal: There may be a rodent or animal that has expired in the walls
Inspect Common Infestation Areas
- Pantry and Storage Areas: Check all dry food storage areas, including unopened packages, for signs of infestation. Pay special attention to items that have been stored for a long time.
- Kitchen Counters and Sinks: Inspect for food debris or spills that may attract pests.
- Fruit Bowls and Trash Cans: Overripe fruits and improperly sealed trash cans can attract pests.
