Merseyside Fire and Rescue Service are warning households about the dangers of reed diffusers.
This comes after one woman had a 'lucky escape' after finding her reed diffuser charred.
Amy left some diffusers on a windowsill, but upon her return she found the reeds burnt and blackened.
The fire and rescue service said this could easily have started a house fire as they were directly below a roller blind.
Sharing a picture of the diffuser, they said: "A concerned member of the public contacted us on social media recently with this photo showing a lucky escape.
"Some reed diffusers had been left on a windowsill and the householder had returned to find them charred.
"This could easily have started a house fire as they were directly below a roller blind.
"Please take care as the weather heats up and make sure these items or any other potentially flammable items are not in direct sunlight."
Immediately, concerned householders commented on the post, with their experiences.
Yvonne said: "This has happened to all six of mine too."
And Victoria said: "This has happened to mine."
