My husband was cutting the grass yesterday and he ran over what looked to be a NEST of cockroaches. There had to be 1000 or more that went in every direction. There were german and american cockroaches out there. We didn't know what to do to kill all of them. Now today,I have noticed 3 in the house and garage but have never had them in here before. Has anyone ever heard of them burrowing in dirt or having a "nest" in the yard? There were lots of leaves in the yard so I am wondering if they were just hiding out there. We live in southern florida so it was pretty warm outside.There seemed to be way too many to just be hiding from the heat, it has to be a nest of whatever it is called where they live. Help please...?????
