Pyrethrins were first registered with the EPA as an insecticide in the 1950s. Since then, it has been introduced into many everyday products to get rid of insects.

In recent years, people have been raising the question of whether or not pyrethrins are safe to use for mosquitoes. Here’s our take on it. 

What Are Pyrethrins?

Pyrethrins are naturally-occurring and found in chemical compounds of some chrysanthemum flowers. 

They are considered nature’s insecticides and help keep plants safe from certain pests.

Are Pyrethrins Safe to Use for Mosquitoes?

Pyrethrins are moderately safe to use at recommended levels, but there are healthier ways to repel mosquitoes. 

According to the CDC, being over-exposed can affect the central nervous system in humans and animals. The effects usually don’t last more than a couple of days, but exposure has been proven to reduce fertility in some animals.

There is also evidence that pyrethrin exposure can lead to developmental problems in babies.

Side Effects of Pyrethrins

While the side effects of pyrethrins don’t last that long, they are serious. Here is how pyrethrins exposure affects humans and animals.


  • Dizziness
  • Headache
  • Nausea
  • Muscle twitching
  • Reduced energy
  • “Spacey” feeling
  • Convulsions
  • Loss of consciousness
  • Trouble breathing
  • Skin irritation


  • Kidney issues
  • Trouble breathing
  • Reduced energy
  • Reduced fertility
  • Coordination problems
  • Skin Irritation

What are Pyrethrins Used For?

Pyrethrins are commercially used as insecticides. Since that is what plants use them for in nature, it’s no surprise that they are very effective.

They’re used for:

  • Crops
  • Lice shampoo
  • Insect repellent
  • Pet shampoo

What are the Alternatives to Pyrethrins?

While pyrethrins are somewhat safe, there are plenty of safer alternatives to pyrethrins.

Essential Oils

  • Cinnamon oil
  • Calendula oil
  • Lemon eucalyptus oil

Avoid the Mosquitoes

While you might not be able to avoid all mosquitoes, you can avoid swarms. 

  • Stay away from stagnant water – Mosquitoes tend to hang around stagnant water and damp or swampy areas. 
  • Avoid being outdoors during dawn or dusk – This may be easier said than done, but mosquitoes are most active during these times. They try to avoid the heat of the day as they can dehydrate and die in high temperatures.
