I was wondering about deet and asthma as well. We never have a problem with my son's asthma when we are abroad but I am a bit worried about spraying him with chemicals that could bring it on
Starry.
I would be worried too.
The percentage of Deet in the products is not reduced for children and at the end of the day you are spraying them with a pesticide.
When they tested Deet on animals (yes, it was tested on animals) for registration, they found no difference in the effects between young animals and adult animals.
Data classes Deet as safe and a low carcinogen...just as long as you follow the instructions that are on every product containing Deet.
Deet was first registered in 1957, after being developed by the US army in 1946......
It had to be re-registered in 1980 and more data/testing on animals done for the registration to be approved in 1988....
Some of the instructions for use and safety advice had to be removed from any product containing Deet......the most relevant to you being that Deet is safe for children.
This is because siezures in children had been reported after using Deet, but as there was no conclusive evidence to prove 100% that Deet caused the siezures, the label and safety instruction were ammended to give clear, commonsense, improved label instructions and warnings on all products containing Deet.
In conclusion, whilst Deet used under normal conditions does not cause a health concern, Deet`s use has been associated with possible adverse effects.
The choice is yours

I know what mine would be if I had a child with asthma.
