Poison ivy is not necessarily the culprit. A number of plants and other things can cause unpleasant reactions. PI is a very likely suspect however and I am not suggesting that you rule it out yet. Poison ivy vines or roots are often underground or under leaf cover, etc. in places where they are not so visible or obvious above ground and sometimes those parts are not so leafy and, thus, harder to notice or to identify. I have inadvertently unearthed PI roots and vines several times when weeding and digging in areas that seemed completely free of PI. Any part of the plant can give you the rash so the underground portions are certainly a problem. I've never heard of poison ivy spewing the poising into the air on its own but if it is burned the smoke is a very serious problem and is one of the many dangers for firefighters in wooded areas. Also, since any part of the plant can be trouble (even after dead) little bits and pieces of it that are not really noticeable can still cause problems. Soap and water should work for cleaning the tools. The trick is being thorough since even a tiny amount of the oil can cause the rash. I would first give a good blast of cold water to the tools before applying soap.

Win 7 Antispyware 2012, Vista Antivirus 2012, and XP Security 2012 are all names for the same rogue anti-spyware program. This family of rogues is promoted in two ways. The first is through the use of fake online antivirus scanners that state that your computer is infected and then prompt you to download a file that will install the infection. The other method are hacked web sites that attempt to exploit vulnerabilities in programs that you are running on your computer to install the infection without your knowledge or permission. Regardless of how it is installed, once it is running on your computer it will install itself as a variety of different program names and graphical user interfaces depending on the version of Windows that is running. Regardless of the name, though, they are all ultimately the same program with just a different skin on it. I provided a self help link, but strongly recommend a malware removal forum lkie Landzdown.

It looks like you have a bermuda lawn. Do not use Roundup, it will kill your lawn. You can spray the entire with a broad leaf week killer. You can get one that attaches to your hose. You may need to spray it a couple of times. That will take care of the weeds that are not grassy weeds. For the grassy weeds it is best to prevent them with pre emergents. They are granular and are applied like fertilizer. If you are in N. TX then you will need to apply that on March 1, June 1 and Sept. 1. If you live in other parts of TX then check with your County extension agency for the proper dates. Keep your grass cut short, 1-1,1/2" . Taller grass will not be as thick. Mow low and mow often. This will help to thicken the grass. Fertilize once the grass start growing well, lightly every 4-6 weeks if you are trying to improve your lawn. Good luck!
