Can House centipedes kill poisonous spiders?

Exactly, @azlotto. And_“all centipedes have poison glands and the means to inject their venom, bites are infrequent and normally do not cause more than temporary, localized pain.“_ Zombie dust bunnies. I can not begin to tell you how much I hate house centipedes.

In my personal experience, Raid® Fumigator Fumigating Fogger’s are, pardon the expression, the bomb. They’re not petroleum based, they’re not temperature dependent, and they don’t leave residue.I don’t know if the directions mention anything or not, but I’d be tempted to leave a ceiling fan on, low, not directly above the fumigator.

@ibstubro…Thanks for your answer, ibstubro

Poisonous is something you consume. Venomous is something that bites!

Neither the spiders nor the centipedes would be there unless there was food for them. Maybe the centepedes are eating spiders, but maybe they’re eating what the spiders are eating too. Your best long term solution is to get rid of the source of food, and also plug the holes where they are getting in.

In the meantime, you can buy- or make spider traps, which would also catch centepedes and other bugs. Here’s a link on how to make one. http://m.wikihow.com/Set-Spider-Traps

There are other ways to deal with these critters. Some are poison (not my first choice) or diatomaceous earth.

PM me for more information. I’m pretty good at thinking through problems like this.

I live in a bare, unfinished, concrete and cinder block basement in a hundred year old building which used to be a factory, and it’s infested with centipedes and millipedes. When I see them, I leave them alone or gently escort them back into the cracks if they’re being a nuisance. They’re pure carnivores and if there’s lots of them, it’s because there’s something else there for them to eat. Knowing that, I gratefully share my living space with them and allow them to hunt freely, just making sure to give my clothing and shoes a few shakes before I put them on.

There aren’t many spiders here (and what few there are here are small and tend to live on the ceiling) which makes me think they probably get eaten by the ‘pedes.

@snowberry…Thanks for your answer and link.

@SmashTheState…“get eaten by the ‘pedes”...I think you’re probably right. Thanks for your answer.

@Joell…So, what category would you put Poison ivy…jk…Thanks for your answer.
