One of the factors/examples that can negatively affect online reviews from users of vacation rentals is the existence of dead cockroaches and other insects in the kitchen and other areas. As part of the cleaning process, you will probably get rid of cockroaches and other insects. However, the life force of cockroaches is strong, and even if they appear to be dead at the time of spraying, they may still be alive. In some cases, they may move out of sight of the cleanup crew.
Cleaning crews have a predetermined work time. There is a risk that a nearly dead cockroach will emerge from the kitchen floor space after that time limit has expired.
Note that extermination of live cockroaches is a must. The owner/operator should not neglect the extermination work, especially in the case of a detached type vacation home, as it requires continuous extermination work.
