Some perfume works as a bug repellant
Perfume might work but DEET or Lemon repellants work better.
Overall, the results from this study confirm that DEET repellents are the most effective mosquito repellents in the market. Although, based on the results from this study, a lemon-eucalyptus oil containing p-menthane-3,8-diol has similar efficacy compared with DEET repellents.But DEET and Lemon based products are best.
