Top Choices for Bug Sprays: What Works and What’s Safe

Picaridin: The Smart Alternative to DEET

Picaridin is like the new kid on the block that’s just as tough as the old-timers. 20% picaridin sprays give you 8-14 hours of protection, about the same as DEET, but without the greasy feel or the worry about ruining your gear. It won’t mess up your plastic tools or fishing gear. Plus, it’s safe for kids over 2 months old.

DEET: Still a Heavy Hitter, But Use with Caution

25-30% DEET is still the king for long-lasting protection (10+ hours), but it can irritate your eyes and damage some synthetic materials. It is safe when used as directed, but it is recommended to use concentrations below 30% for children.

IR3535: A Gentler Option

20% IR3535 gives you 6-12 hours of protection and is less harsh on the environment. It’s a good choice if you’re worried about chemicals, and it’s safe for kids over 6 months.

Natural Options: When You Want to Go Green

Oil of Lemon Eucalyptus (OLE)

30% OLE sprays can keep mosquitoes away for 6-8 hours. Just keep it away from kids under 3, as it can irritate their lungs.

Cedar Oil: The Yard Warrior

Cedar oil is a natural way to kill ticks and mosquitoes in your yard. It messes with their nervous systems, but it’s safe for pets and won’t harm bees and butterflies. You’ll get about 4 weeks of protection, but you might need to reapply after a heavy Maryland thunderstorm.

How to Use Bug Spray the Right Way

  1. Spray Clothes First: If you can, spray your clothes instead of your skin. If you do use it on your skin, use a little bit and wash it off when you go inside.
  2. Protect Your Pets: Use vet-recommended products. Don’t ever put human bug spray on your pets.
  3. Yard Spraying: Let the pro’s at YardGuard Mosquito use our safe and effective products.

Picaridin is a great all-around choice for most folks. Remember to always do tick checks after being outdoors, and talk to your doctor or vet if you have any concerns. Maryland summers are for enjoying, not worrying about bug bites!
