Why is there always this black bug in my room? Flying insects lying on mosquito nets day and night every day! Slow response

This black bug may be a fruit fly, and they are usually attracted by sweetness. Here are some suggestions to prevent and deal with this situation:

1. Keep clean and hygienic: clean up the peels, food residues and garbage at home in time to avoid long-term accumulation, especially the hot weather, which is easy to cause the breeding of fruit flies.

2. Keep it dry: check whether there is a leaking rain or wet place in the home, such as the basement or bathroom, which may easily lead to the breeding of fruit flies. Keeping the house dry and ventilated can effectively prevent fruit flies.

3. Seal doors and windows: Drosophila may also enter the room from the outside, so make sure the doors and windows are well sealed to prevent Drosophila from entering the home.

4. Use insect repellent: Try using some insect repellent or essential oil to prevent fruit flies. For example, put some essential oils such as green onions, cucumbers and citronella in the trash can. The smell of these substances will make fruit flies feel uncomfortable and stay away.

5. Keep ventilation: Open the window regularly every day to keep the indoor air circulating, which will help reduce the number of fruit flies.

6. Use a fly swatter or fly trap: For fruit flies that have already appeared, you can use a fly swatter or fly trap to catch them. Pay attention to pat lightly to avoid pressing the fruit fly on the mosquito net.

I hope the above suggestions can help you solve the problem of black bugs in your room. If the problem is still unresolved, it is recommended to seek the help of professional pest control institutions.
