Lemon eucalyptus oil mosquito repellent

Los Angeles is under invasion by the Aedes "ankle-biting" mosquito, which was first spotted in Southern California in 2001. The population has been growing ever since. Some of my family members have bad reactions to DEET, so I bought Murphy's Naturals Lemon Eucalyptus Oil Insect Repellent Spray. It keeps the mosquitoes away, as long as I reapply it every few hours. — MF
