Spider sightings on the rise across San Diego County

While big and scary, the good news is Orb Weaver spiders are typically harmless to humans, although they are venomous.

SAN DIEGO — Some of the biggest, and scariest looking spiders are spinning webs across San Diego County.

Experts said because of the wet weather we had this year, there is more vegetation, more little bugs, and therefore, more spiders to eat them.

San Diego is specifically seeing a spike in the Orb Weaver spider. They spin incredible and enormous webs that can span from tree to tree, or from your house to your car. They're generally harmless, but they sure look creepy.

"We have more spiders as neighbors, than people," H Suarez said, in South Park. "It's just in time for Halloween! We've actually seen a big uptick in spiders on our balcony," Maria Kalil added.

To find out why we're seeing a spike CBS 8 went straight to San Diego County's top Vector Ecologist and learned our recent rain is to blame.

"More plants means more bugs, which means more food for the spiders, therefore more spiders," Chris Conlan said, who is the Supervising Vector Ecologist for San Diego County.

The typical lifespan of an Orb Weaver spider, is about one year. Their eggs hatch in the spring, continue to grow all summer and by this time, they're adults -- and so are the size of their webs! You won't see as many as it starts to get colder.

"I get a lot more questions about these, this time of year because they're more visible and because of the annoyance factor - walking to their car in the morning and they get a face full of web," Conlan said.

While big and scary, the good news is -- although they are venomous, they're typically harmless to humans.

"The Orb Weavers don't have any interest in biting people," Conlan added.

In San Diego, the Black and Brown Widows still reign supreme and are the bites that require medical attention.

"Those spiders spin webs in corners, not typically in places you're going to run into. If they're spinning a big Charolette's Web type web, that's an Orb Weaver," Conlan said. "They're using a combination of wind and gravity to get these things anchored where they need to go - but those big ones can span maybe six feet, the length of a walkway - no problem."

For many, spiders spark sheer panic, but if you can - spare their life. Those eight legs are designed for the greater good.

"They're catching mosquitoes and flies, and other things you probably wouldn't want in your yard, anyway. They're a good thing to have around," Conlan said.

The advice from experts, to avoid walking into a web, is to put your hand out in front of you - and just feel for it first, so that you're not fully entangled, and have the creepy crawlies the rest of the day.
