It is not luck, and it is not that they are especially clever. German cockroaches have a strong instinct to keep both sides of their body touching something solid at once. That is why they love tight cracks and gaps rather than open space, especially ones close to food, water and warmth.
That is also why spraying the open floor rarely fixes a real problem. The cockroaches are not there. They are in the gap behind the fridge, the crack under the counter, the join where two surfaces meet.
Sealing those gaps does more good than another can of spray ever will.
Spring and summer are when cockroach numbers climb fastest in Gauteng. Worth checking now, before it becomes a problem.
Know a plant or kitchen manager who should see this before the season kicks in?
