We get spiders like that here in S.A. They are called rain spiders - they come out in the summer when it rains lol . They are not poisonous, and rarly bite. BUT my Coffee ate one about 2years ago and got really sick, lethargic and all, the vet said he would not have been affected if he had been bitten but because he ate it he got sick.
We had to induce vomiting and he was ok after a day or two.
I actually like having them in the house, they eat all the mosquitos etc. but I keep the babies well away from them.
