Most-Asked Questions About Mosquito Repellents

Does a homemade mosquito repellent also keep other bugs away?

Yes, most mosquito repellents repel all kinds of bugs: spiders, flies, etc.

Which is better, a natural insect repellent or DEET?

DEET and natural insect repellents are both effective ways to prevent mosquito bites. However, natural repellents are not as effective and long-lasting as DEET. They need to be reapplied regularly for best results.

DEET, on the other hand, is a strong repellent but can have side effects if used too often or on small children. Natural repellents are mostly safe to use with minimal side effects.

Final Word

There are many natural repellents you can try to prevent insect bites. You can use them to protect yourself and your home from mosquitoes without any fear of side effects.

However, if you live in an area with lots of mosquitoes, it is best to use DEET as an insect repellent. DEET offers long-term protection from mosquitoes.
