What Are The Little Black Bugs In My Bird Seed

Last Updated on September 7, 2023 by Susan Levitt

Have you ever noticed little black bugs in your bird seed? If so, don’t worry – these insects are perfectly normal and harmless. As an entomologist, I can tell you that there are many different types of tiny creatures that can infest bird seed, but the most common ones are called weevils.

Weevils are a type of beetle that feed on grains such as wheat, rice, and corn. They often lay their eggs inside seeds or nuts, where the larvae hatch and begin to eat their way through the food source. This is why you might see small holes or tunnels in your bird seed if it has been infested with weevils. While they may be unsightly, weevils do not pose any serious threat to birds or humans and can safely be consumed along with the rest of the seed. So next time you spot some little black bugs crawling around in your bird feeder, know that they’re just doing what comes naturally!

Understanding Weevils And Their Life Cycle

Weevils are a type of beetle that can often be found in stored grains, including birdseed. They range in size from 1/16 to 1/4 inch and are usually black or brown in color. Weevils have an elongated snout that they use for feeding on the grain.

Their life cycle consists of four stages: egg, larva, pupa, and adult. The female weevil lays her eggs inside the grain kernel, where they hatch into small white larvae. These larvae feed on the interior of the seed until they mature into adults. The adult weevils then emerge from the grain and begin searching for new food sources.

One interesting behavior of weevils is their ability to detect potential mates through pheromones. Male weevils release a chemical signal that attracts females from up to several miles away. This allows them to locate each other even when separated by large distances.

Weevils have natural predators such as birds and rodents that help control their populations in nature. However, when they infest stored grains like birdseed, it’s important to take steps to prevent further damage or spread of the pests. In the following sections, we will discuss ways to identify and manage weevil infestations in your birdseed storage areas without harming your feathered friends.

Identifying Weevils In Bird Seed

Weevils are a common pest found in bird seed. These little black bugs, also known as pantry pests, belong to the family Curculionidae. They have elongated snouts and feed on grains and seeds.

To identify weevils in your bird seed, look for small holes or tunnels in the food. You may also notice small black beetles crawling around. Weevil larvae can be identified by their creamy white color and curved bodies.

Preventing weevils from infesting your bird seed is key to keeping it fresh and healthy for your feathered friends. One way to do this is by storing the food in an airtight container made of glass or plastic. This will help keep moisture out and prevent insects from getting inside.

Properly sealing bird seed bags before storage is another important step in preventing weevil infestations. If you find evidence of weevils in your stored birdseed, it’s best to discard it immediately and clean the storage area thoroughly before restocking with new supplies. Taking these preventative measures will ensure that your birds receive only the freshest and healthiest food possible.
