American cockroaches are the big, reddish-brown ones, often over three centimetres long, that people in Hamilton tend to call the outdoor type. They mostly live in drains, garden beds, mulch, compost and the damp ground under older homes, then move inside at night looking for food or shelter after rain. They can turn up in laundries, garages and near floor drains, and are strong enough to fly short distances in warm weather. Because they are bigger and move around in the open, they tend to get noticed and reported sooner than the smaller German type, even when there are actually fewer of them around the property.
Because they live mostly outside, treating just the kitchen will not solve an American cockroach problem. The crew we book looks at the outside of the home first, working out where they are coming from before deciding how to close that off and treat the areas they are using to get inside. Older timber homes on stumps around Hamilton often have more of these gaps than newer builds, simply because there is more open space underneath for cockroaches to move through unseen.
- Inspection of drains, sub-floor areas, garden beds and the yard
- Granular bait and dust placed along common entry routes
- Treatment of gaps around pipes, weep holes and vents
- A targeted spray around the base of the home and garden edges
- Advice on mulch, leaf litter and drainage that draw them in
American cockroaches breed more slowly than the German type, so results usually show inside a week or two as the outdoor population thins out. Ongoing activity often points to a nearby drain or damp patch that is worth asking the crew to check on the day.
