How To Identify a Black Soldier Fly

Soldier flies are large and dark in color. They may have two white patches just behind the wings and have a flattened appearance. Soldier fly larvae and pupae are dark brown and flattened and are about 1 inch in length. 

Where Do They Lay Their Eggs

Soldier flies lay eggs in garbage and other decaying organic material, compost piles and dumpsters. Larvae stay in the site, but will pupate outside of the food source, sometimes around poorly cleaned dumpsters.

Are They Harmful

Black solider flies can often get confused for being a wasp, but they are in the fly family. They are larger in size and can make a loud buzzing noise when flying which can alarm people, but they are actually harmless. Their abdomen tapers to a point that may start to look like a stinger, but no stinger is there. Black soldier flies are actually a bit lazy when it comes to flying. They can often be found hanging out on a sunny leaf.
