Nicole, don't know why I didn't notice your comment originally, sorry. Thanks so much for adding that info! The box of cheap 'rubber gloves' I have doesn't say 'latex free' on the label but they don't seem to bother me, strange. But I mention this because susceptibility of reaction to latex rubber and to latex sap don't seem to be interchangeable. Being able to wear a glove or prophylactic with latex isn't an indication of whether a plant with latex sap will give you a rash. The rash from heart-leaf Philodendron vine is just as bad, but easy to avoid now that I know, just don't touch the sap when taking cuttings. Guttation moisture doesn't seem to cause me a rash, just the sap. I KNOW I was not allergic to this before, I've taken cuttings many times over the many years I've had it around. Excellent point about those foods, thanks! Hementia, thanks! Carol, you never know when the Lantana might 'attack' you more severely! Good plan! DH finagled an outdoor sink for me, from a cracked bathroom sink we found on the curb. It's not pretty, but I can wash hands w/o tromping inside constantly. This bears repeating in italics: "You can develop an allergy overnight to something that has never bothered you before. So strange how that happens." Man, you ain't kiddin'! The only thing worse is not being able to figure out what's going on. Soooo glad I did (at least for now, and possibly partially. I suspect a lot of my 'house plants' have unfriendly sap - to my skin.)

Those are all poison ivy. And big healthy established vines by the look of those blooms! What a job! If it were me, i'd don heavy duty protective gear in 2-3 layers(preferably an outer layer you can toss afterwards), and start cutting away as much as i could while it's dormant and fairly easy to work around. That won't kill it- but when it reprouts at the ground where you cut it off you can hit that with roundup and not damage other stuff. If someone in your family is more resistant to the oils, let them tackle the job. When you're cutting big vines especially, do it slowly so it doesn't splash/squirt sap around. Probably a good idea to wipe down your pruners as they get wet, too. Not sure how 'juicy' it'll be this time of year- i know at other times, the big vines are pretty sappy. It's going to be awfully hard to spray it thoroughly and not get anything else if you don't trim some of it down. You're taking some of the plant's system and weakening it some by trimming. Plus, it takes more spray if you leave it as it is than if you trim. Best of luck! As others have said- be very careful, and wash with technu really well afterwards. If you do end up with a rash, zanafel works pretty well at reducing the time you have it (it's expensive, though). There are a couple of prescription creams that will help tremendously in drying it up as well, and they aren't commonly known. The steroids and shots do work, but i don't like dealing with either one. The dormant vines can still give you a whopper of a rash, and the sap is the worst. If it were me, and this rental had it before you moved in, i'd ask the landlord if they'd knock off a little rent or pay for the weed killers for you. It's a nasty job, and you should get some compensation.

leave of three for PI .. leaves of 5 for this bird spread nightmare ... lol .. that sprig can grow 5 to 10 feet this year ... its just fine in the woods ... but not going to be great.. in your garden .. ken

Poison ivy is ubiquitous around me here in NJ this year! Maybe there has always been the same amount around, I don't know, but I have it all over my property too and I AM very allergic to it. I live at the edge of woods, and apparently that is Poison Ivy nirvana! Have it now in the outdoor shower and roof gutters. There is a product that you can buy that you can apply to yourself after potential exposure to reduce the risk of a reaction if you do get exposed. Had a bad reaction earlier this season to poison ivy. (If you do get it, lay off the mangos as they are in the very same botanical family, 'Anacardiaceae', with the identical chemical compound that causes the rash. (I do eat mangos but avoid them after I have been exposed to the ivy.) The only positive with this thing is that there is research to show that exposure does seem to be related to a reduced risk of SKIN CANCER (probably because your body is on heightened alert in dealing with the ivy reaction). As always, whatever doesn't end up KILLING YOU, MAKES YOU STRONGER! P.S., As an additional clue in the identification, the lower stems on poison ivy will seem slightly reddish... (yes, like its mango kin).
