Tips for Using Lysol Safely Around Pets and Kids

If you have pets or kids at home, you should be more cautious when using Lysol.

The active toxic ingredients can cause serious liver damage to your dogs or cats. That’s why it is not safe to use Lysol around pets.

If you are spraying Lysol, keep babies and pets away from that place. The spray can be in the air for more than an hour, and if the pets breathe in that air, it may not instantly show any effect, but it is unhealthy in the long term. 

That’s why bring back your pets to the place where you have used the spray after a few hours.
