Avoid the Fog

Trying to be a do-it-yourself exterminator(根除者) might save you some money, but if pesticide instructions aren’t followed closely, bugs won’t be the only ones who suffer. Total release foggers, also known as bug bombs, are among the most common products used to kill indoor(室内的) pests. These products work by filling indoor air with a poisonous fog to kill roaches(蟑螂), fleas(跳蚤), and other insects. Over a nine-year period, nearly 3300 people in 10 states became ill from using foggers. The most common mistakes included failing to leave the home during use of bug bombs and returning too soon after application. If you use a fogger, read and follow all instructions.
