Bigger cities means bigger spiders, according to research out of Australia.

Researchers at the University of Sydney say the heat from concrete is part of the reason.

Creepy crawlers in Urban areas also have more to eat and less to eat them.

Researchers in Texas are tested that theory and have some similar findings.

“Spiders that were in urban environments where there was a lot more concrete and a lot more surface area that heats up leading to a little bit warmer temperatures spiders seemed to grow larger. Although the growth was not super-dramatic, there weren’t spiders that were the size of people or anything like that,” said Dr. Blake Bextine, UT Tyler Biologist.

Dr. Bextine says even if spiders do get bigger, it does not necessarily mean they will become more venomous.
