Depending on the level of infestation in your home, you may need to call in a pest management professional. There are a number of things to check before signing a contract and before letting the company into your home.

Choosing a pest management company

If you are a tenant, you are required to notify the landlord as soon as possible if you notice a problem with insects or other pests. Close cooperation between you, the landlord and the pest management company is essential to resolving the situation.

During pesticide application

Make sure the company complies with the signed service contract, as well as with pesticide application regulations:

  • No one but workers applying pesticides can be on the premises or exposed to the pesticide used.
  • All necessary measures must be taken to avoid contaminating all surfaces or objects that will not be treated.
  • No pets should be exposed to the pesticide. Keep children and pets away from the area during spraying and cover aquariums before spraying begins.
