Why not give your sheds and garages a spring good clean.
Throw out old bird food, grass seed (any potential rodent food! Check for rats or mouse nests! Check for evidence of rodents (droppings)
Check for Queen wasps and thier starter nest (golf ball shaped and sized greyish balls hanging up from ceilings or off walls)
Clean the floors removing rubbish etc.
The tidier your shed the less inviting to pests!
