Significance of the study:
Is to find and invent a mosquito killer which is effective and are cheaper to other pesticides.
This study can also be tried and expermented at home.
Scope and Limitation:
This study is limited on the making of mosquito killer with the use of lemon grass.

While you have considered allergic reactions to DEET, people can be allergic to species of lemon grass (Cymbopogon spp, including C. ambiguus). Reactions include severe skin rashes and blistering.

Just because chemicals such as essential oils (terpenoids like citronella) can be sourced from plants, it does not entail that 'natural' products are entirely harmless or risk-free.
