Inside buildings cockroaches use a wide network of supply ducts, cable channels and
cavities to spread. As many other species of pests, cockroaches have the natural
ambition to expand and, without any countermeasures, a building is completely infested
after a short time. Cockroaches eat everything. They eat high quality foods as well as
leftovers from the day before or waste. They can even survive in places without food.
There they live on microorganisms, fatty deposits or similar materials. Cockroaches
are potential carriers of diseases and infections. With their bodies they catch bacteria,
viruses and fungal spores, which they get rid of on their paths. As nocturnal insects they
move in areas at night where we as humans demand the highest level of hygiene.
In apartments or homes special attention should be paid to the potential migration
paths of cockroaches:
Drain pipes (washing machine, dishwasher, sink etc.), regarding washing machine and
dishwasher - in particular the space between pipe and hose. All other unnecessary openings
should be sealed, for example with silicone. Ventilation shafts (such as in bathrooms):
ventilation openings should be equipped on the inside with fly screens. Possibly existing
gaps under and alongside the entrance door: they should be closed or covered, for example
with thermal insulation tape.
