Sydney pest manager Dennis Kokontis shares his experience of tackling a cockroach infestation using two Bayer products.


Cockroaches are common in commercial premises associated with food production or handling, as well as public buildings and domestic premises. They pose a serious threat to human health, emitting allergens that worsen asthma symptoms and transmitting disease pathogens causing gastroenteritis, typhoid, dysentery, poliomyelitis and other ailments.

Dennis Kokontis from PestFree Sydney was recently contracted to service a hotel for a cockroach infestation and contacted Wendell Arnett, Territory Sales Manager (NSW/ACT) at Bayer for assistance. The hotel in question was a multi-storey building with an underground car park, loading dock, two bars and a fully functioning kitchen. The previous company had used cockroach gel without a great deal of success, so Mr Kokontis was keen to try a different product.

Mr Kokontis carried out a thorough inspection of the building to ascertain the level of cockroach infestation. The inspection revealed that the issue was with both American and German cockroaches. The majority of the infestation consisted of German cockroaches in the inside bar and kitchen area and American cockroaches in the underground car park, loading dock and pool area.

“After our thorough inspection of the hotel premises, the recommendation was to use Temprid 75 Insecticide spray in conjunction with Maxforce Fusion Cockroach Gel,” said Mr Arnett. Temprid 75 has long been a go-to product for PestFree Sydney to help gain control of pests in both commercial and domestic premises. However, this would be the first occasion Mr Kokontis had used Maxforce Fusion gel.

“Maxforce Fusion was recommended because it is different to other cockroach gels on the market, as it contains TLC technology (Total Lifecycle Control). It contains a feeding stimulant within its bait matrix that not only targets adult cockroaches of all sizes, but also targets nymphs,” explained Mr Arnett. “The stability of the formulation allows for easy spot size management as well. In this case, we were able to treat smaller cockroaches with one or two spots five millimetres in diameter and larger cockroaches with two or three spots of the same size.”

The bars and kitchen were treated with Temprid 75 and Maxforce Fusion, with Temprid 75 being used as a residual treatment for the car park and loading dock areas. A follow-up inspection was carried out two weeks later to check on the treatment.

“Mr Kokontis was impressed with the outstanding results of Maxforce Fusion, saying it’s now standard procedure on all his residential and commercial treatments,” said Mr Arnett. Mr Kokontis believes its unique formulation helps with the initial knockdown and maintenance of his sites while Temprid 75 is an excellent choice for residual treatments.

“We highly recommend Temprid 75 and will continue to use it, as the results speak for themselves,” he said. “However, we have noticed vast improvements in numerous sites that were once infested after using Maxforce Fusion,” Mr Kokontis explained. “Maxforce Fusion is one of the best cockroach gels on the market as it stimulates the feeding of cockroaches and has given us proven results.

“Overall, PestFree Sydney is very impressed with all of Bayer’s products,” he said.
