There are hornets flying around near the balcony bamboo poles

Hornets want to make nests in bamboo poles, and if you can't find someone else to help you, you can try to solve it yourself: put on winter clothes.

Specialty, long riding boots, wear leather gloves, wear a winter motorcycle helmet, so that you can enclose yourself and arm, and then boil a pot of boiling water to the balcony, close the balcony door (to prevent the wasp from flying indoors) and pour boiling water into the hole above the bamboo pole, so that the wasp can be scalded to death, don't forget to take the bamboo pole away and replace it, otherwise other wasps will smell the smell and will come.

Good luck.

It should be burned with fire, with a bamboo pole in front of it, cotton alcohol, etc., but pay attention to fire safety and self-safety.

Call the landlord to deal with it, he rents a house for you, and is obliged to provide a good living environment.

You call 110 and they'll solve it, and they say that there are hornets that can't get in by themselves

It's a dry toilet, and the reason why there's black stuff, and there's flies, and you should know that the flies' babies are born there. There is also a black thing called Locke, and they eat some common creatures in the toilet, so as long as it is a dry toilet, it can't be served.
