Answer: What you see are little spittle bugs. They produce the foamy coating to protect themselves from the elements and from predators. You can hose the spittle off with water which will discourage them. Spittle bugs have two or three generations a year in Florida. The adults lay eggs on the thatch at the base of your turf and the nymphs feed on the grass blades (while hiding under their spittle). If your turf has excessive thatch, you have a perfect breeding ground for these pests. Follow approved practices regarding mowing, fertilization and irrigation to reduce thatch buildup. If a thatch problem exists, dethatching should reduce spittlebug problems. Avoid over-irrigating turf to minimize infestations. Spittlebugs will not survive drought conditions. Best wishes with your lawn.
