It can be a bit disconcerting to find small black beetles at home, but these insects are quite common, whether one variety or another, can be found in most homes. Fortunately, most types of these small beetles do not cause major damage and it is easy to get rid of them.
One variety of this household pest that can be adapted to the description of “small black beetles” is the common carpet beetle. Because they feed on natural fiber fibers, cereals and pet food, the vast majority of households contain at least a few of these animals. Carpet beetles reproduce very slowly, so they rarely become apparent or become a problem. These insects do not bite, carry diseases or much less damage the structure of the home.
Weevils or broad-nosed billbills are another very common variety of black beetles. Unlike rice weevils, these bugs feed on food that they find on the outside like roots and vines, and only enter homes to fend off harsh weather conditions, especially in the summer. They tend to be attracted to moisture. Because your food is not in the home, they will disappear on their own.
The most troublesome type of small black beetles you can find in your home may be insects that eat grains, which come in different varieties. Sometimes they are mistaken for flour beetles, red beetles or rice beetles, but the beetles enter the homes by means of the products we buy. Adults of the vast majority of varieties can live for more than a year, and literally hundreds of insects can live in a box of grains. It is common to find this type of pests in the pantries or wherever flour, cereal or pet food is sold. They can migrate from one box to another and lay lots of eggs.
Prevention and extermination
The best way to get rid of carpet beetles is by regularly cleaning and buying pantry and pet food items in containers where light enters. Pesticides are not necessary.
Pesticides are not necessary to get rid of weevils, either. The best way to prevent them from entering the home is by sealing and caulking all cracks and all joints around doors and windows. They can also be easily removed by vacuuming or sweeping, or by using deep water containers as traps around the perimeter of the house.
Pesticides are not recommended to get rid of these types of pests because they can infect areas where food is stored. Once the infestation has been discovered, it has all grain products that are not stored in lighted jars. To prevent further infestations and to isolate unborn larvae, store all grain and dry food products in lighted jars such as jars or plastic tubes. This will prevent pests from migrating from boxes or thin plastic bags. Keep pantry and kitchen clean after cooking.
