Is it haram to kill a spider

Salam, I have really bad arachnophobia which is fear of spiders so they way I remove them unfortunately is by killing them. Now I’m very conflicted as to whether this is allowed in Islam mainly because of how they played a role in keeping Prophet Muhammed safe and as a kid I was taught to not kill them. Yet I read on another website that it is allowed. I just wanted to get a proper answer to help ease my thoughts. Jazakallah Khair
