How many insects are enough for my infestation?

One approach is to inundate your infestation with as many releases as is affordable during the first couple years of introduction. After that, one should make additional releases in isolated areas in future years. This method is the most dramatic. It reduces the time, in years, for an insect to build up and disperse to the limits of your infestation.

Another approach is to release insects into your most critical areas in the first year. Then, reinforce these releases with additional insects in future years. This method strives to achieve a balance between what is affordable and the degree of infestation in your area.

The least costly approach is to introduce one or two releases into your infestation and do nothing more. This method will get a colony started. It may also take many more years for the insect to distribute itself throughout your entire infestation.
