* Install bird spikes: Bird spikes are physical barriers that can be installed on the roof of your shed or on any other surface where birds like to perch. These spikes will make it uncomfortable for birds to land, and they will eventually stop coming back.
* Use bird netting: Bird netting can be installed around the perimeter of your shed to prevent birds from entering. Be sure to use a strong netting that is resistant to tearing.
* Apply bird repellent: There are a number of commercial bird repellents available that can be applied to the roof of your shed or other surfaces where birds like to perch. These repellents will emit a smell or taste that birds find unpleasant, and they will avoid the area.
* Remove bird nests: If you find any bird nests in or around your shed, be sure to remove them. This will discourage birds from coming back to nest in the same area.
* Keep your shed clean: Birds are attracted to food and garbage, so be sure to keep your shed clean and free of any food or trash that could attract them.
* Install motion-activated sprinklers: Motion-activated sprinklers can be used to scare birds away from your shed. When the sprinklers detect motion, they will emit a spray of water that will surprise and scare the birds away.
* Fake owl decoys: Fake owl decoys can be placed around your shed to deter birds. Owls are natural predators of birds, so the sight of an owl will often be enough to scare them away.
By following these tips, you can help to stop birds from pooping on your vehicles in your shed.
