It is very helpful everywhere where horseflies cause a lot of problems (summer cottages, pastures, farms, stables, beaches ...) Horseflies are the main problem in summer country life. These are very annoying flies that bite quite noticeably. Horseflies cause a lot of trouble, both for people and animals. They are active almost the entire warm period of the year from April to October. Even with a moderate attack of horseflies, cows reduce milk yield by 10-15% and quickly lose weight. Scientists have calculated that the loss of strength in animals that are bothered by horseflies and flies per day is equivalent to the undernourishment of 400 grams of oats per head of cattle. In a herd of 700 cows, the milk shortage per day is 1,500 liters. Our trap, called the BioTrap trap, effectively controls the number of horseflies and reduces them to a minimum. The trap is placed outdoors and works without chemicals or electricity. Extensive testing has shown a 90-95% reduction in horseflies in the area around the trap! How does the trap attract horseflies?
