I am looking to cover about 20 square metres with a weed mat and was looking to put some mulch on top of the mat. But I am told, mulch almost always attracts cockroaches. Can't put hay because that will attract the rats. Gravel is too expensive.
What kind of mulch does not attract cockroaches ?
Any ideas on what I could cover the weed mat with ? Just slightly aesthetically pleasing is what am after.
Cheers,
What did the guy at the garden supply centre suggest when you called him?
