Oak processionary experiment with bird houses for the great tit has been carried out since 2016. It has been observed that the great tit likes to eat the young, not yet hairy caterpillars in the month of April. In serious cases of contamination, the use of relatively mild chemical pest killers has been allowed by local authorities. Because chemicals may be harmful to other insects, an alternative is the use of vacuuming equipment to remove the caterpillars, followed by incinerating the caught specimens.

Natural hazard human activity. Disease is a natural hazard that can be enhanced by human factors such as urbanization or poor sanitation. Disease affecting multiple people can be termed an outbreak or epidemic. In some cases, a hazard exists in that a human-made defense against disease could fail, for example through antibiotic resistance. Each of the natural hazard types outlined above have very different characteristics, in terms of the spatial and temporal scales they influence, hazard frequency and return period, and measures of intensity and impact. These complexities result in "single-hazard" assessments being commonplace, where the hazard potential from one particular hazard
