I've heard of people who catch, or even buy spiders, to bring them into their homes to kill bb's.
I have always liked spiders for some reason....and have never felt threatened when seeing one. The fact they combat bb's is the best reason of all to LOVE them!!

(It does not sound like a great idea to me, but I would like to hear more.)

I love the idea of hunting nymphs with spiders. It's like you have a miniature attack dog keeping away tiny intruders. Did you name him/her?

They aren't a method of control because the real control methods will kill them also. Do not add to the spider population but don't subtract either. You need to ID them though.
I checked and this particular spider is a typical SoCal Hololena. It is a funnel web spider harmless to humans. It found it's way in and I am leaving it be just keeping it off the kitchen counter.It can stay in the kitchen to eat what it can find.

I can't remember if it was on here, or elsewhere....but I do remember it catching my attention when I read it.
Obviously not a good idea unless they are a "harmless" (to humans) breed of spiders....which I would assume they are. Around these parts where I live all the spiders are harmless.

I have never heard of spiders as biological control for bed bugs either. But then again some folks do the strangest of things on the basis of its only table top science what could possibly go wrong.
My favourite used to be the horror story that went around school about the factory worker who lost an arm trying to unblock a drain using a plunger and cocktail of 3 or 4 house hold cleaning products. It always had a morbid fascination until I met the man one day.
I think we can set aside the concept of spider release until we see something posted that can be cross referenced and at least sanity checked.

Bed Bugs LimitedActually David there is data...
From Usingers Monograph pages 31 and 32..
Various spiders have been reported feeding on bed bugs. Povoln)
ound that a colony of C. lectularius on bats in a castle at Austerlitz was
destroyed by Steaboda bipunctata (L.). Another interesting case is the
claim of Lorando (1929) that a spider, Thanatos flavidus Simon, destroyed all the bed bugs in refugee camps near Athens between 1923
and 1925. Hase (1934) confirmed the effectiveness of this spider in laboratory
tests but warned that predators were not a practical solution to
bed bug control under ordinary conditions.Lorando's claim was mentioned in the BB report by the Ministry of Health in 1934. I haven't been able to find Lorando's paper though.
That spider is a type of running crab spider Philodromidae and my Gravatar is a USA running crab.

As Jeff White explains on BB Central spiders a general predators and will not hesitate to eat a BB if the encounter it while hunting. Releasing a bunch of spiders isn't going to work as a control measure but allowing those already in the house to live and pick off an occasional household pest will not hurt.
Of course there are some I would kill, Black widows, Brown recluse, yellow sac, and Hobo spiders can have clinically significant bites.
BTW Jason, in the Pacific Northwest you guys do have the hobo spider whose venom is similar in effect to the infamous brown recluse.

I'v'e never heard of venomess spiders here in Vancouver, BC.
Maybe in Washington State, or Oregon, but not here. I could be wrong but i've never heard of anyone having them here.
Interesting article you posted. So it does seem as though spiders will kill bb's if they encounter them.

Interesting article you posted. So it does seem as though spiders will kill bb's if they encounter them.Spiders are indiscriminate predators. Anything is fair game, including cannibilism, for a hungry one that prowls or falls into the web of a web builder.
The fact the will eat a BB isn't in doubt but efficacy as a control is not possible.
Prey always outnumbers predators in nature thous so the only good spiders or centipedes may do is pick off an occasional one. The aforementioned running crab spiders, not the specific one but the same family, are often found in boxes of crickets used to feed reptiles.
However I have said no one gets "infested" with spiders. If a place has a lot of them you need to see what they are eating that is keeping so many around.
My little friend wandered in through the kitchen window and keeps appearing on the counter and I relocate it to the floor about once a week.
