Congratulations on having your own bed and breakfast! It is a wonderful way to make a living, and at the same time meet interesting people making their way through your town or city. One of the things you will need to maintain is cleanliness, which I am quite sure as an owner of an establishment you already excel at. Unfortunately, whether or not you clean the place well; the fact that you serve food will attract different pests and critters who will mess up the place for you.
The best thing to do is to maintain the services of a Pest Control Company Greenville for preventive treatment every month or quarterly, depending on the location of your business. This will chase away what small amount of pests decided to live in your establishment while at the same time deter most others from doing so in the future.
You cannot skimp on this as this will be important for when the surprise health department checks occur. Sometimes, even though your place looks incredibly clean, there are actually a good number of pests living around the area, in the dark corners where you never thought to check. If the examiner from the health department discovers this, you will lose your standing as a quality business.
