I can't post a picture my phone won't let me, but basically I have all these tiny little red spiders (tiny) all over my white front door and windowsills outside. Google is saying I think mites or something? I just sprayed everywhere with dettol but I can't wipe it as if I kill one it leaves a big red stain and will look like a murder scene at the end of it! I don't want them infesting my home.
