At this point, it's worth introducing a short educational note. In the image above you will see two different species of cockroach. The top guy is Drymaplaneta Semivitta, otherwise known as the Gisborne cockroach; the woodroach (forestry term); or more commonly as the "aaagghhh there's an enormous cockroach in the bedroom/kitchen/bathroom". While they can be disturbing for some people to encounter unexpectedly at close quarters, this roach is absolutely harmless. People don't like them but they're solitary and they have no bad habits in terms of infesting food, carrying disease etc. If you have them inside, it generally means they want to get out of the rain. We at Green Agenda quietly admire them as being a high order bug, right up amongst the praying mantises, cicadas and dragonflies.
The other guy is Blattella Germanica, better known as the German cockroach and also "those horrible little brown ones that scuttle around behind the fridge" - he's potentially more of a problem. These guys do actively seek food to infest and they can carry disease in the right circumstances. If you have them inside, you ought to act decisively to eradicate them from your home.
If you have cockroaches of any variety, just give us a call, and we'll move them along quickly and quietly, and using the right technique to match the species.
