A widespread standard in pest control is the use of pesticides. Here, pesticide is a collective term for the subcategories biocides and plant protection products. Biocides are used to control harmful organisms, but not to protect living plants. These include, for example, wood preservatives or rodenticides. Plant protection products, as the name suggests, are used to protect living plants from pests. The use of such preparations promises rapid and widespread control success. In agriculture, a wide variety of pesticides are used to protect crops from damage by insects. However, the use of insecticides poses great risks to humans and the environment. Often, treated foods are contaminated with preparation residues that we ingest when eating food. These pollute the human body and can even increase the risk of cancer.
Another risk is the unintentional pollution of our waters. Often, not 100% of the preparations reach their intended place of use, but are washed away by rain directly after use and thus end up in our rivers. In the example of agriculture mentioned above, crop protection products are necessary because of the high financial pressure on the industry and the need to avoid possible crop failures or crop reductions.
In the private and professional pest control environment, however, there are many alternatives to the use of pesticides. Especially when it comes to acute control of an active infestation or the removal of wasp nests, the use of biocides is often not necessary. Common practice is still powders or pesticide sprays that contain toxic ingredients (often nerve agents) and that end users can still buy on the Internet or in stores. However, if the wasp nest - as is so often the case - is located in the roller shutter box of the child's room or bedroom and dust is used here, these nano-particles are also deposited automatically, uncontrolled and above all invisibly on pillows, sofas, carpets or behind furniture and thus constantly penetrate our organism via our skin or through our lungs and cause damage. Especially for children this is very dangerous and therefore associations and consumer protectors have been fighting for years to have these products severely restricted or banned. In the common practice of professional SBK companies, these products are almost no longer used anyway.
Frost sprays specially developed for pest control can provide infestation control of insects or wasp nest removal in an ecological and humane way using a thermal process. The sprays deliver a burst of spray at a temperature of up to -45°C. Thus, pests are shock frozen within a few seconds and can be removed afterwards. The process shock-freezes the water in the insects' cells. These cells then expand and burst. Unlike conventional control methods, this results in a quick and humane kill of the insect. The spray kills pests reliably and above all directly - and not only individual insects, but also huge nests, as many videos on Youtube of professional SBKs as well as the growing order volumes clearly prove.
For acute control of bed bugs, the thermal method with frost sprays is particularly suitable. Although the insects are able to adapt to cold outside temperatures for several weeks, the organism is unable to process the extreme cold of -45 °C. The insects can be controlled by the thermal frost method. Another relevant advantage of the thermal frost method is that it can be used to control not only the adult insects, but also to destroy the bed bugs' eggs. With conventional biocides for bed bug control, elimination of the eggs is not possible. This results in many follow-up treatments and rarely complete removal of an infestation. The above-mentioned dangers that biocides also pose to the human body must be considered particularly critically in the context of bed bug control. Bed bugs occur there in areas such as pillows or mattresses.
Biocides may only be used if strict precautionary measures are observed. These measures are not least associated with high costs if the infested areas, for example in hotels or hospitals, are used commercially. In such cases, it is not possible to rent out the treated rooms for several days. After a thermal treatment, on the other hand, a room is immediately available for use again.
From our own experience, we have been able to accompany a well-known hotel from weekly biocide treatments - which was certainly not a nice effect for the guests - to frost treatments and thus a) could save a lot of money, since they could apply the biocide-free alternative themselves, b) had the infestation under control very soon, since the frost also attacked the eggs, while the biocide never eliminated them and c) could create a harmless, toxin-free environment for the guests, which served the health and recreation of all.
Wasp nests are often removed with the help of the insecticide pyrethrum. Pyrethrum is a neurotoxin that affects not only the target organisms, but also the user and other non-target organisms. Professional pest controllers know this, when in summer after a day with 5 wasp nest controls the head hurts. The thermal method with frost sprays can be used here as well. Some of the sprays are supplied with a foldable adapter, which serves as an extension and concentration of the spray. This adapter can be poked directly into a wasp nest and the spray applied with pinpoint accuracy inside the nest.
Commercially available frost sprays can be used to control both conventional nests and ground nests and individual insects. The size of the nest is independent of this. On Youtube or in specialized forums on the Internet, you can find numerous examples of huge nests (human-sized) that have been successfully treated with frost methods.
Of course, this method is also suitable for pest control in the private environment, since these sprays are available on the market without a permit and freely for sale. However, it is important to observe the species protection regulations prior to control and, in case of doubt, to obtain information from the responsible veterinary office or a competent pest controller. Field reports show that professional users like to use the product as an alternative and are convinced of the process in the long term.
