Grow your fingernails out! My thumb nail and middle finger are the two nails that I use for this. Fingernails work perfect when they are grown just beyond the end of your finger or just before the end. Makes it easy to hit the roach without buring your fingers. No need for hate just something I just thought that I would throw out there. Toke on GC brothers and sisters.
A lot of people don't like long nails. Use the stems of leaves from trees, or your keys work as well.
