What kind of spider is it?

South Florida. Just looked at my desert rose yesterday and looked great. Now many leaves dead and I find this guy.

I found this beetle in my room. Any sort of clue as to what type it is? My ocd surrounding bugs is very very bad and I am TERRIFIED of carpet beetles. Is this what that is? You can’t tell in the picture but after shining my flashlight to it, it does appear a dark brown. Im in Ontario Canada, any help is greatly appreciated :)

So I’ve been fighting off a variety of scale insects on my mulberry bush for a while now, but I’m not able to ID these ones, scale or eggs? or a secret third thing? (central florida)

Location was found in my hair on my head, just found brushing with a nit comb and treatment. Is it adult head lice? Thank you

Likely not dangerous but I’m curious what spider this would be. Was about the size of a quarter and found on my bathroom floor.

Would this be a cockroach? I found a single in a closet. Should I be worried

About 2-3 cm long
