One of the most annoying things about having a swimming pool in the backyard is the attraction it brings to wasps. Wasps like the proximity of the swimming pool because it provides them easy access to water. However, this is not ideal for you simply because wasps are naturally defensive and they can feel threatened even by you simply trying to enjoy your own swimming pool. Here are four tips to help you steer them away:

1. Build a Decoy Nest: The first thing you should do is build a decoy nest that you always leave up by the pool somewhere. Since wasps are territorial, they are less likely to want to build a nest close by. This usually deters them completely in order to find a better location with no wasps, but still with a heavy food and water supply. 
2. Create a Different Water Source: If you're having trouble keeping the wasps away still, you can create a different water source somewhere in your yard. This could include a pond or fountain. Since the water here is more natural, the wasps will likely choose this over your swimming pool, especially when your swimming pool is used often. The wasps would prefer a water source that is left for themselves. 
3. Build a Trap: If you are really having trouble with the wasps, while this is not the most pest friendly option, you can build a trap. This is easily done by cutting a water bottle is half and filling it with fuel, which wasps are attracted to. Once they land, they will drown here and the job will be done in getting rid of them fairly easy. 
4. Get Rid of the Nest: If all else fails, getting rid of the nest itself is probably the best way to get rid of the wasps altogether. However, this is challenging and should definitely not be done on your own. Hiring professionals with the right tools will also have the right gear to wear and defensive experience to protect themselves from stings. Hiring a professional who works to relocate the nests is also the best for both natural extermination methods, as well as pest friendly. 

With these four tips, you can be sure that there is surely one method that will work for removing wasps from your pool. This way, you don't have to worry about them being such as huge nuisance that it affects your ability to enjoy your own swimming pool.
