I used expanding foam insulation about 3 weeks ago and also didn't read the instructions first. Got it on my fingers and hands and didn't think it would be so hard to get off. I was sure I'd just surf the internet and find a handy solution to my problem, but no, --- all those answers all amounted to "it will wear off in a few days." Yikes, we were now getting ready for church, where we start out with a greeting/sharing of the peace which, of course, includes shaking hands. Well, I was embarrased!!! I won't forget to put on the gloves first the next time I use that stuff.
I get rid of ants with Terro ant killer. If they are the "grease" ants, just take a drop of vegetable oil and stir it into the liquid ant killer. Always have great results with their product.
