Jorō Spiders: Pretty, Big, and Not Very Bitey Two new studies offer good news about Jorō spiders: Common spider control products are effective against them, and their bites are both unlikely and generally harmless.

Well...it turns out that the stuff in dish soap degrades the cuticle of most arthropods (including beneficial insects). I don't know how long the residue persists from that, but it's not completely safe for non-target stuff. Careful application is key, as you know!

They’re Huge, They’re Creepy, and They’re Back—An Expert’s Tips for Joro Spider Season An entomologist answers your questions about the Joro invasion this fall.

Joro spiders want 3 things: to not be touched or held, to not be in your house, and to not bite you.

Great new article by Gayoung Lee @gizmodo.com!

I'm not saying that stuff doesn't work (we tried it, and it does) but I'm a state employee so my official company policy is to recommend folks only used labeled products.

Entomologists have been saying this for a while, but new evidence published confirms: Joro spiders are not a major health risk. See original thread for link to research papers

They're definitely negatively impacting native spider diversity. Our team has been conducting our "spider surveys" for 4 years now and there's a clear impact of Joros on native orbweavers: more Joros = less (or often no) native orbweavers. We'll probably publish this info after this season.

Chemical management strategies for the invasive Jorō spider, Trichonephila clavata (Araneae: Araneidae) Abstract. Historically, spider management has received relatively little attention in the literature compared to insect pests, and few studies have examine

Want to get rid of Joro spiders? This #bioinvasion can be managed using commonly available products. Sure, other things work, but please just stick to the labeled stuff (i.e., don't spray machine lubricant all over the place). New #openaccess study in @entsocamerica.bsky.social's JEE provides info.

Keep calm and carry on: bites from Trichonephila clavata are unlikely and cause minimal discomfort Abstract. Arachnophobia is a widespread phenomenon, despite the fact that the vast majority of spiders pose no meaningful threat to people. The introductio

Will Joro spiders (a #bioinvasion in the SE US) bite you, and if they do will it hurt? Turns out they won't bite without a LOT of provocation, and their bites are akin to a mosquito bite - some redness, swelling, and largely gone in a day. Study is #openaccess in @entsocamerica.bsky.social's JME.

Bridging Borders to Battle Invasive Species: Reflections on an International Fellowship in the U.S. Through a fellowship in South Carolina, a scientist from Jersey learned from experts, built collaborations that will advance invasive species response on both sides of the Atlantic.

Super psyched to have a bunch of our ALB work come out in this special issue! #bioinvasions

Modelling biological processes can be hard, and even harder when scientists and land managers aren't on the same page. We need better communication between these groups, especially with #bioinvasions. Communication matters, y'all.

Concur, most of us do. Also many just suck at returning emails in general, which might explain the radio silence...

The boxtree moth was recently found in several new states (MD, VA, WV) and is likely to keep spreading. This #invasivespecies is a recent #bioinvasions that threatens boxwoods - a very common landscape plant. This OA paper in @entsocamerica.bsky.social's JIPM gives a good summary of this pest.

Large chunks of people's favorite trees seemingly go leafless overnight this time of year, usually thanks to caterpillars. Our paper (w/ @kellyoten.bsky.social & #nobluesky Robert Jetton) in @entsocamerica.bsky.social's JIPM highlights several species in the SE US: academic.oup.com/jipm/article...

I agree! I think it's a nice piece of work and it definitely gets read. Thanks for leading the charge!

I love this figure in our review of sawflies of eastern North America. Shout out to @flydrocarbon.bsky.social for leading the charge and the @catherinelinnen.bsky.social lab!

YouTube video by FNRClemson Kudzu Identification, History, and Control

The hot, humid, dog days of summer in the southeastern U.S. means the #invasivespecies kudzu is in out and in all it's glory. Not familiar with this weed? Wondering why we care about this #bioinvasion? Curious as to how to get rid of it? This video might just help...

How do you get rid of invasive Elaeagnus in a forested landscape? We found that you have to get herbicide to the stem or stump because the drooping growth pattern creates an umbrella, preventing good foliar coverage. A simple, yet useful study!

TAKE OFF, EH.

Emerald ash borer is on the move again (though truth be told, it's not all that surprising...).

New work in the @entsocamerica.bsky.social's Journal of Economic Entomology examines an eruptive native herbivore, the baldcypress leafroller (Archips goyerana), in the southern U.S. (aren't baldcypress swamps cool?) and shows they're more common than we thought...

Everyone loves getting a box o' hornets!

I was fortunate enough to take part in the Kentucky Forest Health Conference earlier this month. Nearly 300 people gathered to learn all about #foresthealth and #bioinvasions issues in the state. It was great to hang out with old friends Ellen and Abe, too!

This is the most surreal thing I've ever experienced. Like, just, WTF is even happening.

A few of my favorite slides from my #ISAT2025 talk where I spoke about using social media to help with #invasivespecies and #bioinvasions messaging. Also the first time I used the word "bunghole" in a professional presentation, so there's that. #iykyk
