Yellow Mealworms

Yellow mealworms as larvae are typically cylindrical with yellow/brownish coloring around the body. These pests are usually a half an inch long, growing to be up to a full inch. As they age and mature, their exterior shell becomes harder. They also begin to look more like beetles and less worm-like over time.

Yellow mealworms typically appear in neglected areas of the house, often in spaces with high humidity. They especially like bagged items in kitchen pantries that have been left unbothered for a while. Stored food that becomes damp or moldy are hotspots for these creatures. A female mealworm will deposit eggs in grain products which can lead to a bigger infestation.

The most common food sources include damp, decomposing, or moldy substances, such as dead insects, animal waste, or stored grains that have decayed. If you were to find mealworms in your pantry, they would likely be located in oatmeal, flour, or other dry products that typically are stored in large quantities. They will hide in damp, moist, and cool areas where food sources are located nearby.

There are a number of steps you can take to try and remove mealworms. Try and locate the source of food and shelter first. Be aware that this is likely old grain products in your pantry, especially items you haven’t used in a while. Sometimes, simply vacuuming to remove bait or throwing away food sources may be enough to remove mealworms. However, you may experience the problem again if they are finding ways to enter your home. In this case, contacting a professional is going to be the most beneficial way to get rid of the source.
