Implementing an integrated pest management plan is not a one-off occurrence. A multi-stage programme is required to rid an affected data centre of unwanted visitors and ensure they do not return. Here are eight points to consider when establishing your own pest control strategy.
- Identify the target species to eradicate. The most common infestations are due to cockroaches, ants and spiders. Sometimes insects such as crickets are the problem. Occasionally other species like geckos are lured in to eat the original pests.
- Modify the environment to stop pests from entering the data centre. Fully seal around doors, vents and cable/pipe penetrations. Periodically inspect ingress points for signs of seal wear or breakdown.
- When engaging the services of a licensed pest control professional, make sure they are familiar with the specific requirements of a data centre.
- Get rid of the active infestation. Although vacuuming can remove insects in accessible areas, insecticide is still required to kill pests in harder to reach areas. Aerosol sprays are not advisable for use in data centres. These chemicals are corrosive and their mist could easily enter operating equipment and cause damage. Use encapsulated gel baits instead. A gel bait is a sticky mat that is enclosed in a plastic box or envelope with different lure materials available which appeal to sugar-feeding or protein-feeding insects. The number of baits per given area is dependent upon the type of pest and the degree of infestation. Place baits where pests are likely to congregate and feed. Draw a map of where the baits are placed to make follow-up easier.
- To break the cycle of reinfestation when eggs hatch, monitor baits fortnightly and replenish as needed. A different bait may be required for maintenance after the initial cleanout phase is complete.
- Locate and remove any source of nesting material to discourage formation of future generations.
- Inspect incoming boxes and other materials for pests and avoid storing unnecessary items in the data centre.
- Don’t forget to treat the outside of the building. Select a pest control method which is safe for wildlife. Avoid applying pesticides near areas where chemicals could enter the building such as air intake vents.
