Anong mas effective, off lotion or mosquito patch?

According to my kid's pedia, yung off lotion daw ay hindi advisable for babies 2 months below kasi it has a DEET content which has a bad effect sa skin ng babies. I think for babies na 2 months below, okay na muna yung mosquito patch. Yun din ang gamit ko sa baby ko pero medyo ilayo mo sa face nya para hindi nya malanghap yung amoy. :)
