Flies are insects that are active frequently during the day and have obvious phototropism. At night, it perchs still. Activities and habitats depend on fly species, season, temperature and region. In some seasons, stable rot flies, summer side flies, and city flies also invade the house. The big-headed golden fly, the mercerized green fly, the fly, the volley fly, the hemp fly, etc. are mainly active and inhabit the outdoors.
Flies mostly feed on spoiled organic matter and are therefore common in poorly hygienic environments. Flies have sucking mouth organs that contaminate food and spread diseases such as dysentery. In ecosystems, the larvae of flies play an important role as decomposers of plants and animals.
When summer comes, flies have become one of the pests that many families have to worry about, and most people use screens, fly shoots, and insecticides to deal with them.
But have you ever thought about catching flies with your bare hands? Although it sounds disgusting. In fact, this is not "no learning", as long as you understand the principle of fly take-off, you can greatly improve the probability of success.
The domestic video team "Slow Point Video" was revealed through slow motion, it turned out that the fly initial flight speed was 1km/h, and in 0.03 seconds, it left the ground and spread its wings, and the angle of the flight route and the ground was often less than 40 °, and after 10mm off the ground, it was changed to an oblique angle.
Taking the reaction time of ordinary people as 0.1 seconds, using high school mathematics and physics knowledge, after a series of calculations, it can be concluded that if you want to accurately catch flies, you need to be in a circle with a radius of 1cm or 2cm from the ground.
The secret is: hand in a half-grip shape, approach the fly, and then aim at the fly to quickly sweep across, so that you can cover the fly's escape route. Be careful not to buckle directly downwards, because in rare cases the fly will take off vertically, and when it is buckled, the fly has flown horizontally out of the palm of the hand.
Poison bait is a simple, economical, quick-acting and easy-to-use method of fly control. Within a few hours, miraculous effects can often occur: flies that are resistant to dichlorvos, etc., can be controlled by 0.1-0.2% of the dichlorvos sugar water bait depending on the route of drug entry. In addition to mixing food bait as poisonous bait, there are also liquid poisonous bait, viscose poisonous bait, granular poisonous bait, etc., which can be used for different occasions.
