This is probably an extremely dumb question but I need some advice on how to catch Turkistan roaches to dust with multivitamin to feed my veiled chameleon. I have one of those cricket feeder rocks that I can put the multivitamin in and dust them with. I also have a plastic cricket counter but I cant seem to scoop them up fast enough and they also get away as soon as I dump them into the feeder rock. I am too slow or they are just too fast for me lol. Any suggestions?
