About 7 months ago we laid a new turf (just a small area under the clothesline, the rest is paving and gravel and garden beds), and 5 weeks later Army worms almost demolished the lot before I finally recognized what was causing it. Killed them all (it was war!). Then about four days ago I noticed our now healthy turf had dead spots that were FREAKIN' SPREADING! Did the water check on one spot and yes, the buggers are back, one came crawling out of the turf away from the water. So last night I blitzed the lawn again with insecticide and came out this morning to - don't be squeamish, now - dead bodies on my lawn. It's a crime scene of poisoned Army worms. Damn, I hate them!
