Even if you don't like it, it still is a necessary part of the overall cycle of life

We have all seen a group of buzzards around a dead animal. It is heartbreaking and nauseating to see but it is an important part of the Eco system. You may not like spiders but they are helping to keep the bug population in check. Even snakes are helpful in keeping the rat population down to prevent them from spreading disease. Now mosquitoes on the other hand have no positive purpose at all. At least none that I can think of. The cycle of life has a purpose but it brings both joy and pain. Accepting things that you don't understand is necessary too. Like the serenity prayer says "God grant me serenity to accept the things I cannot change, courage to change the things I can, and the wisdom to know the difference."
