I've been spotting some of these insects in my house lately, they look like spiders but it seems like they have six legs and antennae instead of eight legs. Can someone tell me what insect is this? Is it dangerous? I don't mind having them in my house but if they're dangerous I might have to do something.
Their body seems to be relatively flat when you look at it from a side, the location is Costa Rica, we are in the wet season (no winter,summer,etc. here) but I'm almost sure I've seen them during the dry season as well, also, the insect's body size (ignoring legs) is similar to a thumb. In case that helps to indentify it.
