ADVERTORIAL Lab and feld studies confrm Cryonite efcacy and Cryonite specialist with Silvandersson The study proves what we already know Freezing technology is a great alternative to pesticides and Cryonite is versatile far from eradicating only bed bugs Some technicians even use it against sea tulips Pyura spinifera on boat hulls There are more uses for Cryonite than many PMPs realize About the feld study Four RIFA mounds were selected and two Cryonite systems were used Each site was prepared with a plastic tarp shovel and probe Each was treated in a slightly diferent procedure and evaluated In the researchers opinion the most efective observed mortality 95 percent was the method used approaching the mound with a plume from the lance while plunging the probe into the bottom of the mound from a downward angle of 45 the lance tip inserted into the hole left by the probe and full injection held for 15 to 20 seconds Other procedures were attempted with favorable results In a recent feld research study conducted by the American Academy of Entomological Sciences AAES results supported a 95 percent efcacy rate of the Cryonite system for mortality on mounds of established colonies of the red imported fre ant Solonopis invicta or RIFA in their natural habitat Although not widely used by pest management professionals PMPs nationwide the Cryonite system has for years been known as an environmentally friendly alternative with a high efcacy rate for eradicating a broad range of insects by using freezing technology and dry ice Early laboratory studies show that none of the many examined species survived a temperature below 22 F regardless of life cycle stage The same study also concluded that the faster the cooling speed was the lesser coolness was needed to achieve mortality in general This also was true for pests perhaps lesser known as suitable for Cryonite treatments such as moths and museum four tobacco and grain beetles With these facts in mind it was perhaps not surprising the efcacy rate was close to 100 percent for RIFA according to the feld studies conducted by AAES Insects can be immune to toxins but it isnt possible to be immune to mechanical methods says Henrik Björkqvist a PMP The researchers recommend the procedure be done as deeply as possible not below the depth of the mound base to ensure the Cryonite plume travels up and to the side channels for the highest efcacy The time should be extended to at least 30 seconds depending on the size and depth of the mound The researchers suggest that treatment commence by initiating the lance trigger aiming it at the mound opening to kill escaping ants while the probe is being inserted at the downward 45 angle as far as possible and then insert the lance tip For additional information contact Dr Jefrey Brown at AAES at americanentomologyacademy@ gmail com or 850 499 7961 1 855 527 4601 sales@ silvandersson se
