I found some of this spiders while changing some plugs on houses in the Lajas Valley. Most or all of them had eggs sacks and were inside crevices and dark places on the houses that were getting ready. Non showed aggressiveness or ran. They just stood in guard beside their egg sacks. The color of the spot was more orange than red and have stripes all around the legs. Can say if they are poisonous or not but remember that they are Black Widows.
