A few simple preparations make flea foggers more effective. Since flea eggs tend to hide in carpets, vacuuming the carpets before fogging causes the eggs to hatch, improving the chance of killing fleas. Removing cushions from furniture allows the fogger to penetrate deeper and get rid of fleas in the cracks.
Pets and humans should leave the home for three to four hours after setting off a flea fogger. Upon return, it is advised to open doors and windows, allowing the home to air out.Learn more about Invasive Insects
