There are many flies in the open-air bakery in the shopping center.

First of all, the sanitation around the shopping mall is definitely not very good, and the humid basement environment is easy to breed mosquitoes and flies.

Secondly, because it is open, it can't stop flies from flying.

Third, because it can't be sealed, it is impossible to completely kill flies.

In a word, only a closed environment can kill flies and establish a relatively hygienic environment.

Considering the cost, we can refer to the practice of open-air stalls and build a greenhouse with steel pipe structure (measure the length, width and height, buy steel pipes or triangular irons, find a welder to weld hooks, and fix the connecting pipes with hooks). This temporary building is easy to dismantle and transport, and the most important thing is that it is not illegal. The steel pipe structure can be wrapped with propaganda cloth, and some slogans such as bread pictures or preferential activities can be engraved on it, which looks more beautiful. The business surface can be covered with transparent plastic curtain, so that customers can see the on-site production inside and ensure the freshness.

It will be effective to consider killing flies after doing the above: physical methods, fly-killing lamps or fly-killing stickers can be used to kill flies during business hours during the day, because customers don't want to see chemicals enter the bread; After closing at night, you can use chemical methods to light incense or spray mosquito repellent. Of course, these can also be used. If the greenhouse is demolished at night, it is not necessary.

Please adopt the best method after considering the surrounding environment and cost performance.
