Growing flowers and grasses indoors and balconies will inevitably cause some small black flying insects, at the beginning, only a few of them will buzz in groups after a few days, not only the plant leaves are bitten, but they are also particularly bold, always flying around in front of people's eyes.
The scientific name of this small flying insect is "thrips", and its eggs are laid in the mesophyll tissue of plants, and the average human eye cannot see its existence. When the indoor ventilation is not smooth, dry and high temperature, the eggs hatch into adults, nibble on the leaves of the plant, suck the sap of the leaves, in a few days it will breed the next generation, lay more eggs in the leaf tissue, and then after just a few days a new batch of small flying insects will take off, so repeatedly, the number of small flying insects grows geometrically, outbreak.
The usual method of killing is to use drugs to spray, although the effect is fast, but in a few days there will be thrips taking off, so go to spray, so that our living room environment must be followed by suffering, the residue of the drug invisibly becomes an invisible killer of family health. Therefore, the author strongly discourages the use of drugs to culling thrips indoors.
In terms of the author's practical experience in raising flowers and planting grasses for more than 20 years, using the armyworm board to deal with small flying insects is a good method. The appearance of the sticky insect board is very much like a yellow double-sided adhesive paper, tearing open the seal on both sides will reveal the yellow bottom plate, both sides of the bottom plate have a strong stickiness, coated with insect attractants, can attract the small flying insect and stick to it close to the ground, so that it can no longer fly. Casually hanging the armyworm board somewhere, does not occupy space, no odor is generated, no harm to people, although it can not completely and completely kill the thrips, but can effectively control its outbreak, so that it only exists sporadically, the number is controlled within the range that both humans and plants can tolerate.
The author used an A4 paper-sized stickworm board, in a four- or five-square-meter enclosed balcony, only one winter stuck thousands of small flying insects, just imagine if there is no use of sticky insect board, what kind of scene will be a scene for thousands of small flying insects to fly? I'm going to crash!
Therefore, friends who love to raise flowers, hanging a small sticky worm board, can really solve the big trouble of small flying insects.
