Why flies multiply in June
It's not the heat itself — it's how fast generations turn over when it arrives.
The impression that flies appear suddenly and in large numbers is only partly misleading. At around twenty-five degrees Celsius, the complete life cycle of a housefly from egg to adult takes little more than a week. Each successive generation is many times larger than the one before it — hence the avalanche effect.
That is why responding only once flies appear almost always fails in June. By the time the flies become noticeable, the next generation is already developing.
Operations that generate organic waste are most vulnerable: food manufacturers, food service businesses, grocery retailers, and livestock facilities — as well as ordinary country houses in summer. The key to control almost always lies not in the products, but at the source: closed containers, regular waste removal, and no decaying scraps.
Products address the other half of the problem. Sticky ribbons remain the simplest and most straightforward format for indoor spaces — they require neither calculations nor precautions and work continuously. Aerosols and sprays are used where rapid results are needed.
