Can I fix this myself?

I have a hole where the cement was on the corner of my house. I have a slab foundation. I meant to fix it years ago but then a snake moved in so I’ve ignored it for many many years. It’s time to get my home ready to sell and I can’t seem to find anyone that wants to fix it. Is it just as simple as sorta cleaning out the hole and putting some quickrete or something in there? I’ll put a pic in the comments of said “snake hole.”
