Setting up bug barriers, | keeping things clean, and keeping down any other insect | populations that they'd feed on seems to deal with most | everything else. Tiny bugs like boxelder bugs show up rarely, and | are small enough that I can squish them without much trouble, but | anything bigger than an inch is tough to deal with. | | So if I'm likely to find one of these on my wall in my living | room (even just occasionally), I legitimately need to plan ahead | and figure out a one-person strategy for killing/moving them out | of my house in a way that it isn't traumatizing, and if | conventional bug barriers don't work to keep them out then I need | to figure out something else for reducing the likelihood of them | coming in the house. | | If they're just outside, that's not so much of a problem, big | bugs are fine outside, although it'll likely put a bit of a | damper on my willingness to go hiking in wood trails given | people's descriptions of the webs. | | ---- | | [0]: Yes, I know house centipedes are positive predators to have | around and shouldn't be treated as pests, but I need to be able | to walk into my bathroom without worrying I'll find one on the | wall. | pg_bot wrote: | I live in SC and have seen some of these spiders.

I assume they don't die inside of there. | | I have a vacuum with a detachable wand, but I've never really | used it for insects because I always felt like... now what? | Can't they just crawl back out? | | Also slightly skeptical of a handheld grabber or my vacuum's | ability to handle a 3 inch spider, but maybe I'm | overestimating their grabbing strength.

Huge boon if I'll mostly only need to worry | about them when biking/walking. | mkr-hn wrote: | No Joro spiders inside so far. At least 50 _around_ the house, | going by webs, but none inside. They kept their distance | outside. | throwanem wrote: | Orb weavers rarely enter human dwellings, although they do | quite like porches for the combination of good web substrate | and the prey-attracting effect of porch lights and lit windows. | | I've only had an orb weaver in the house a couple of times, and | once ushered back out they typically remain so. One of them, a | young red orb weaver, abseiled down from the ceiling onto my | bare shoulder - I'm not sure which of us was more surprised, | but even if I didn't like spiders quite well in general, I | think her evident terror upon realizing her mistake would have | aroused some degree of sympathy. | | Most spiders you'll encounter indoors in the eastern US will be | cobweb spiders, of which family black widows are by far the | most famous - but also very rare, with more typically | encountered cobweb spiders being quite harmless to humans. (Of | course, so are widows, when given proper respect, as with the | one who overwintered behind the toilet tank one year when I was | ten or so. She kept to herself and so did we, and we all got | along fine - and they are such beautiful creatures!) Beyond | that you can expect the occasional wolf spider, salticid, or | the like, these being cursorial hunters and thus not so much | homebodies as spiders generally tend to be. | blakesterz wrote: | "They likely traveled across the globe on shipping containers, | similar to the Bubonic plague." | | Seems like an odd choice to compare a spider and the Bubonic | plague. Wouldn't any number of invasive species have been better? | throwanem wrote: | "Invasive" is mostly a matter of perspective. | | By far the most successful invasive arthropod in the Nearctic | is the European honeybee, but you never really hear anyone talk | about the considerable ecological harm those do, for the | obvious reason that their agricultural and thus economic | utility is considered far to outweigh the externalities of | their cultivation. | smhenderson wrote: | The whole article is a bit tongue-in-cheek, with it's | references to "terrifying" even though it also says they're | harmless.

I emailed the UGA professor about this and he was | surprised to see they had already came this far in. | | Almost 4(edit) years later, when you go outside on a misty | morning during the summer, you look up into the trees as you | drive home and it is literally nothing but glimmering Joro spider | webs. Thousands of them. | | Most of them now appear in my back yard as I removed those trees, | but it was crazy to see peoples faces when they walked to my | front door and realized what they were walking past and freaked | out at a 3 inch spider about 5 foot away from them. | | edit: when I looked up the UGA professor name I realized I | emailed it back in September 2018!
