Fighting house ants is an extremely difficult task. Many methods are ineffective, others are applicable only in some cases.
Domestic ants reproduce throughout the year, they prefer warm places with high humidity: bathrooms, kitchens, bathrooms. These little insects are known for their extraordinary ability to penetrate everywhere.
House ants live in cracks in walls and ceilings, under baseboards and parquet, behind tile coverings. They can be found among book sheets, in piles of flax, in cereals and nuts.
House ants are omnivorous: they eat sweets, meat products, live and dead insects, they damage clothing, fabrics, skin, insulation of household appliances. They are attracted to the smell of sweat, they can even crawl into wounds on human skin.
I really consider house ants to be malicious insects, which penetrate everywhere, and can ruin the life of the homeowner.
My grandparents and later my mother insist that the best way to fight with the domestic ants is the search for the nest of ants, the destruction of the uterus and the ants that work there. It is true that it is very difficult to do this, since the ants are very small and can hide anywhere, but try to follow the movement of the insects and find the nest. Before you open the anthill, buy ordinary dichlorvos for a direct hit since you literally die in a second.
Another trick is that you can sprinkle the ant nest exit points with ground black pepper, and they will no longer appear in this location.
If the ants have settled in your house, I hope you can attack the problem, so that it does not become something that disturbs your comfort.
