Decoy Wasps Nests

This is probably the easiest way to keep wasps away. All you need to do is create a decoy nest by placing a few pieces of paper inside a plastic bag.

You can even go as far as creating a fake wasp nest by cutting out a piece of cardboard and putting it inside a plastic bag.

Once again, put the top of the bag tightly shut and place it somewhere where wasps might find it.

You’ll notice that when wasps come across the decoy nests, they won’t bother to investigate further. Instead, they’ll simply fly back to the original nest.

As such, you can rest assured knowing that they won’t return to your real nest.

This is because wasps are very territorial by nature and won’t want to go near a rival nest. Therefore, once they’ve found a suitable spot for their own nest, they’ll stay there until they die.

You should try doing this during the springtime, when the wasps are not awaking from their wintertime slumber.

Ultrasonic Pest Repellents

If you want to get more creative, then you can opt for ultrasonic pest repellents. These devices emit sound waves at extremely high frequencies.

When these waves hit an insect, they cause vibrations that eventually kill them.

Ensure that you purchase one that emits sound waves between 3KHz and 10KHz. A range to high for humans to hear but powerful against wasp and many other backyard pests.

This device will also get rid of many other insects from your decking. For example, you may find that spiders and ants are repelled by the sound waves.

You can also attract more wasps by placing a joint of beef away from the decking and your guest’s food.

Wasps are attracted to anything that smells good. So, you should ensure that you clean your plates regularly. Otherwise, you may find that they start attracting flies as well.

Wasp Traps

These traps work by making the wasp think that it has found a suitable nest. Once it has done so, it will enter the trap and die. There are two different types of wasp traps:
