Where do gnats come from?

Of all the abundance of insects in apartments, two or three species of gnats most often settle. The most common are fruit flies, or fruit flies. They are usually found in spoiled fruits and vegetables – they are attracted to the smell of fermentation.

– Drosophila is a model object of geneticists, thanks to this fly the structure of DNA has been discovered and now many scientific and medical discoveries are being made.

In addition to fruit gnats, other insects are found in houses.

– In apartments you can often find sciaridae (mushroom mosquitoes) living in the soil in pots with indoor plants. These are small, less than 1 mm, black gnats, their larvae develop in the ground. They do not harm plants, only aesthetic dislike, – says Mikhail Krivosheev. – Worse are whiteflies, plant pests – their larvae feed on the sap of indoor flowers.

Many gnats are attracted to moisture. They love to live in basements and any places where it is damp, rotten or moldy. Therefore, by the way, gnats often appear where garbage is taken out.
