Last week I noticed a small little area in the ground(soil) in my yard where there were many cream coloured tiny ants...I never saw them before. I thought they were termites but there is no wood nearby. Yesterday all those ants turned into ants with wings. There were tons of them. I sprayed the area with "RAID" and killed them all. Does anyone know what the cause of these are...it appears these ants live in the ground they were crawling out and hatching into winged ants. Will they eat roots of plants e.t.c. and cause any damage?
