How do you kill fleas in shed?

To kill fleas in a shed, start by thoroughly cleaning the area: vacuum all surfaces, including corners and crevices, and dispose of the vacuum bag or contents outside. Use an insecticide specifically designed for fleas, following the manufacturer's instructions carefully. Additionally, consider using diatomaceous earth as a natural option, applying it in areas where fleas are likely to hide. Finally, treat any pets that may have been in the shed to prevent re-infestation.
