Hi-Yield Bug Blaster Bifenthrin 2.4% is not really selective in the insects it will kill, so if lighting bugs contact a treated area long enough to receive a lethal dose they could be killed. Earthworms are pretty protected by the mucus on their bodies so generally it would not harm them and it would not have any effect on lizards when used as directed. You may notice a decline in numbers of lizaerds in the area though as you would be killing the insects that are their food source.
