Do Mosquito Repellent Expire: Best Usage

Mosquitoes are annoying and they can be hazardous. To protect yourself from mosquito bites, you need to use mosquito repellent. But do mosquito repellent expire?

Mosquito repellents work by using chemicals that smell like chemicals that mosquitoes don’t like. There are several different types of repellents available in the market these days and they all have different ingredients. Some of them contain DEET while others use picaridin or permethrin as their main ingredient.

All mosquito repellent products have expiration dates printed on the back of their packaging. While the length of time that they’ll last depends on the type of product, sprays tend to expire sooner than lotions or gels, it’s always better to err on the side of caution and toss any expired spray cans out for good measure.

Always Check The Back Of The Repellent

The fine print on the back of a repellent product will tell you how long it’s good for and most products have an expiration date stamped on them. But once you’ve opened it, how long will it keep working?

The effective life of a mosquito repellent differs by type. Some are more time-sensitive than others. Mosquito gels and candles can last for most of a decade if sealed correctly. This is because they contain pyrethrins, which degrade rapidly when exposed to air or sunlight (like in their original packaging). Other sprays may lose effectiveness in two or three years but still provide some protection against mosquitoes during this period.

Less Effect After Two Years

Most sprays and lotions will tend to lose their effectiveness after two to three years, but gels and candles can last for most of a decade if sealed correctly.

If you decide to use an older spray, make sure that it’s at least six months old before opening it up. If the container is damaged or leaking, toss it out immediately, it probably won’t work anymore anyway.

If you’re not sure about your repellents, throw them out.

  • If it smells bad, it’s probably bad.
  • If it has a strange color, it’s probably bad.
  • If it doesn’t work, it’s probably bad.
  • If it’s not in a sealed container, it’s probably bad.

Use Of Natural Repellent

You can use a natural insect repellent like Oil or Lotion of Lemon Eucalyptus which has been proven to be effective in many studies. Natural ingredients have been used for centuries and are safe for children, pets, and the environment.
