Where can I get mosquito repellent patch which are suitable for newborn? My LO is 5 weeks old.

I used to tiger brand patch but my girls still continue to get bitten when we go outdoor. Then, my GP tell me to use apply on type with DEET instead of the patch. Only those with DEET then can effectively prevent bites from dengue and zika mosquitoes. This brand is certified safe for babies and I bought from clinic.
