It depends on what the bugs are...if they are mosquitoes, you can get rid of them by circulating the water. Mosquito larvae need still and stagnent water to survive. Not too many other types of bugs will live in the pool water, but many types will use the pool as a water source, so they are living near the pool. You need to include more information in your question such as do they live in the water or do they congregate around the pool, what do they look like, where are you located...etc. More information?
