Can I use this on mattresses that people sleep on including children?
Answer by • Sep 28, 2018
This can be used on all surfaces of upholstered furniture, but it's recommended to avoid spraying to the point of wetting as this can be dangerous - a fine mist or spray applied uniformly is all that is necessary to kill fleas and ticks.
What surfaces should be treated? Is it for all (hard and soft) surfaces or is this primarily intended for rugs, carpets, bedding, and draperies?
Answer by • Jan 22, 2018
You can use this spray on both soft and hard surfaces. A fine mist or spray applied uniformly is all that is necessary to kill fleas and ticks.
