An apparatus and method for detecting wood eating insect infestations. For trees, a baseline air sample is taken outside of the tree to determine a baseline CO2 concentration. A second CO2 sample is taken from underneath the bark of the tree. The results of the sample taken from underneath the bark of tree are compared to the baseline sample. An increased CO2 indicates a hidden wood eating insect infestation somewhere in the tree, even though the location of the infestation may be far removed from the place of sampling. For a shipping container, a baseline sample of air near the CO2 container is taken, then a sample is taken from the bottom of a shipping container. A shipping container need not be filled with wood products, rather wood products only be present as packing or support materials. The comparison is made between the baseline CO2 with the CO2 sample taken from inside the shipping container. An increased CO2 concentration is an indication of a hidden wood eating insect infestation inside the shipping container.
