What is the best way to get rid of German cockroaches in restaurants?
I am a pest controller in Sydney, Australia. I spray Temprid on skirting boards, under the appliances and fridges and cookers, then use gels in cabinets, corners. Is that effective? Thanks
When dealing with roaches, treatments should be limited to cracks, crevices and wall voids as this is where roaches spend most of their time. Using a combination of roach bait, insecticide, and an insect growth regulator will usually be needed.
- Apply roach baits such as Avert Dry Flowable or MaxForce FC in cracks or crevices where roach feces have been found.
- Apply an insecticide dust such as Delta Dust into wall voids where plumbing pipes exist and in wall voids behind stoves or dishwashers. These walls are most likely to have cockroaches hiding inside because of the humidity provided by the pipes.
- Liquid insecticides combined with insect growth regulators will also offer some control. Temprid SC and Gentrol IGR are labeled to spray in food handling establishments for roach control. (ALWAYS READ PRODUCT LABELS BEFORE APPLICATION) Precaution should be used when applications are being performed. Apply in cracks and crevice at low pressure setting, being extremely careful not to splash or allow runoff that could potentially contaminate food prep surfaces. Protective barrier applications of insecticides such as Temprid SC should be made on a regular basis on the outside of structure to exclude insects from entering.
