There are several types of black beetles, such as the carpet beetle or the ground beetle. These beetles don't care whether they are indoors or outdoors, which can make them a real problem. You can expect to see black beetles popping up around springtime. They will look for pollen to eat, including on flowers inside your home. They can lay their larvae in bird nests and wool sweaters. If you spot these black beetles, get rid of them before you have a complete infestation.
Clean your house. Remove any dust or lint that you see lying around. Make sure you get all corners, under furniture and even behind your radiators. This will prevent your black beetles from having a place to lay their eggs.
Look outside for any bird or animal nests. Remove them if they are infested with black beetles or if you see any black beetle eggs. Up to 50 eggs can be laid at one time.
Keep up with your pet hair by vacuuming frequently. A small pile of pet hair is a great place for the black beetle to lay eggs.
Use an insecticide with the ingredient lambda-cyhalothrin if you still have black beetles after removing all nesting locations. One gallon should cover up to 1,000 square feet. The insecticide can be used both indoors and outdoors. Be careful not to spray the insecticide near food or on plants that you plan to eat.
Repeat the insecticide treatment two more times; you will need to wait two weeks in between each treatment. You shouldn't have a problem with the black beetles after this.
