One of the advantages of current-generation pesticides is that they are less potent, meaning they put you and your pets at less risk. The other side is that they can take longer to work. After a spray, expect four to six weeks before the pest problem goes away. A typical pest control application will last around 90 days.
If outdoor applications experience constant or heavy rainfall, their effectiveness may be affected and will last about 60 days. Pesticides used to treat flying insects, such as mosquitoes or flies, last about 30 days. For a general application of preventive pesticides, it's best to do what professionals do and apply it every 90 days for continuous monitoring. When an exterminator applies insecticide to my house, how long does it last? Do I need it repeated every month, or every 6 months, or what? Pest control services suggest a set amount of time to stay away from home once work has been completed.
Once the service is complete, you may generally be advised to stay out of your home for around 2 to 4 hours. However, this can vary depending on the type of service and can also extend up to a maximum of 24 hours. These lists are by no means exhaustive. You will need to coordinate with the pest control service to ensure that you are truly prepared and receive the best service.
