Controlled Atmosphere Treatment

100% natural insect treatment

B-Cat Insect Treatment builds Controlled Atmosphere systems to control insect infestations in food commodities.  

Low Oxygen Atmosphere

A Controlled Atmosphere system makes it possible to create a Low Oxygen atmosphere in a gas-tight

Killing all insects, in all life stages

Our natural treatment system is based on the principle no oxygen, no life. That’s why we call our Controlled Atmosphere system ZerOx®.
By reducing the oxygen level in a gas-tight room to less than 0.5%, the system is able to achieve a 100% mortality rate for all insects in all development stages: eggs, larvae, pupae and adults.

Natural & residu-free

Controlled Atmosphere / Low Oxygen Treatment is completely safe and natural: since no chemicals are applied, no (toxic) residues remain on the stored product and insects are unable to build up resistance. This natural treatment method meets the strictest regulations for fumigation, including those that apply for organic food supply (EEC 2092/91 and NOP).

No oxygen, no life

Food commodities

A Controlled Atmosphere system is suitable for all types of dried food products: rice, grain, seeds, corn,  nuts, beans, legumes (e.g. lentils), concentrates, dried fruits, tobacco, coffee, tea, cocoa, spices, herbs, sugar and more. The system is not suitable for fresh fruits or vegetables, which still consume oxygen. 


O2, CO2, humidity & temperature

Depending on the type of food product, and on the type of insect pest, it may be necessary to manage different conditions in the gastight room (or tent, or container). With a ZerOx® system it’s possible to control O2, CO2, temperature and humidity.
