This will vary based on the type of pest issue that you are experiencing. One-time applications for your general crawling insects (ants, crickets, spiders, etc.) we typically recommend blocking at least an hour of your time for our technician to come in, inspect, and treat your home. With other pests such as roaches or bed bugs, we will normally recommend 90 minutes to 2 hours, but this would be depending on the severity of the infestation and the size of the home or area that we will be treating. Most maintenance services will average 30-40 minutes each service.
