I stopped at a small engine shop on my way up north Monday and he confirmed what RebelSS said. I got some yellow tubing and after struggling for almost 1/2 hour, got the lines reconnected and went out and whacked some weeds. Thanks for all the replies.
Last Friday, I saw a beetle at my home's carpet. It is very difficult for me to get rid with this beetle and I also saw some eggs were laying on the carpet, which was quite damaging. Then on a recommendation of my neighbor I had called up the Queens NY pest control services, who had used an insect spray and where the experts spray around the floorboards, furniture and on carpets and helped us by preventing the carpet beetles laying their eggs and removing all the food sources.
Actually the guy at ace was pretty close. These little guys are for framing steel studs before sheetrocking, but yes they also could be for sheet metal work even though they are black . But your right hawg sharp and go in fast.
