I was at a lecture this week where the speaker suggested doing just that. He was talking about when you paint stumps with round-up, but I don't see why you couldn't add it to a spray container. I'd just make sure I was wearing something I didn't care about in case a gust of wind blows the dye back at you.

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.

I just want to give an update on my poison ivy. After due deliberation and much consideration I decided I could carefully target just the poison ivy leaves with an Ortho poison ivy killer without it getting into the ground. I began with a small area first and waited to see what would happen. At first I thought perhaps it had no effect at all, but then a few weeks later I noticed that tiny patch I'd sprayed was brown and dead. So I sprayed the rest. It took a lot of patience and a couple of rounds to get it all and is a slow process just as daninthedirt said, but it looks as though it has finally succeeded! So my next step will be removing that patch of dirt and hopefully removing any roots with it and then bring in some fresh dirt. I figure that's the best way to assure I'm removing as much poison residue in the soil as possible. I'll wait awhile before doing this step to give the poison a chance to complete its job on that root system. I, of course did these courses of poison during long stretches of dry weather so it didn't wash off the leaves. Next time this problem arises I'm going to try the vinegar recipe method for comparison. Thanks for all the help and good advice!
