Please come to your home to help you sanitize, they have this service.

If nesting has been confirmed, you should seek the local fire department or call the 119 fire department for consultation, there have been reports that the Chengdu area receives more than 2,000 alarms a year to remove nesting wasps. If you are still in the early stage of nesting, you can consider using mosquito coils and dried wormwood to light it, remove the wall cover, and regularly use the minimum displacement to smoke and discharge, but do not fumigate from the outside of the flue mouth to avoid wasps from getting into the house ......Late summer and early autumn is the peak season for wasps to nest separately, so you should pay special attention to this time, and contact a pest control company for indoor fumigation and insect control if you can detect the traces of wasps or other pests (such as termites or cockroaches) early.
