I killed two bugs today

I killed two bugs and I think one was a mosquito and the other was a fly. I sprayed them continuously with lysol and some foaming cleaning product. I kind of feel bad.. What if that fly had a family? Maybe his kids are looking for him. I don't care about the mosquito though, they kill more people than people kill mosquitoes. speaking of bugs I think I saw a spider earlier in the bathroom. I'll ask my mom to get rid of it though, I hate spiders.
