As with all cockroach control programmes, an
integrated approach involving the use of monitoring traps, insecticidal baits and well
targeted use of contact insecticides where appropriate is recommended. Night time
inspections may be necessary in difficult to control infestation situations in order to
identify key harbourage areas. Harbourage denial and proofing are also effective. |
