How do I know if the materials that a pest control operator is using are safe?
First, make sure that any company that you hire is reputable, licensed and well trained to ensure that they are knowledgeable and responsible in handling pesticides. Pesticides by their nature are designed to kill and therefore cannot be termed “safe”. They can, however, be used responsibly. Ask your pest control service provider to show you the labels of products he/she is using. That will tell you the ingredients and levels of toxicity. If you are still confused call the manufacturer for product information.
