Construction Sites

Whether you’re renovating an older-style building, or constructing entirely new, redesigning your building’s structure can be exciting. However, if the right precautions aren’t taken, new construction can also attract unwanted attention from pests.

To help prevent pest issues during construction and ensure your facility does not become home to pests once construction is complete, our Training and Technical Specialist, and entomologist Jennifer Brumfield explains how you can build pest management into your construction plans.

There are a variety of proactive measures your facility can take before, during and after the construction process to accomplish this, she explains:


“Before construction even begins, it’s important to get two people on board: your pest management provider and your contractor. An experienced pest management provider can do more than prevent and manage pest infestations that pop up during construction….

“When involved from day one, he/she can also provide feedback on building materials and locations that will be the least attractive to pests, and help you build measures into your construction plan that will lead to a successful pest management program when the doors to your new facility finally open,” she said.

Several tips your pest management professional may provide include:

icon  Use non-cellulose building materials to deter termites.
icon  Consider applying a preventive termite barrier to the property.
icon  Use pest monitors to assess pest populations in the surrounding area.
icon  Understanding which pest species will be a threat will help you determine what steps you need to take to deter them.
icon  Understand geographic conditions.
icon  Selecting a location for your facility near a water source might create additional pest pressures.
icon  Sufficiently grade the property to prevent puddles from forming around the foundation.

Remember, moisture attracts pests like mosquitoes and termites. Even though your management team may be the ultimate decision maker, it will be up to your contractor to take the lead on pest management during his/her work.

Check for mosquito breeding in the following places:-

icon  Discarded receptacles and building wastes in the worksite, bangsal area and site offices.
icon  Building materials, canvas sheets, equipment and machinery.
icon  Puddles on the ground
icon  Puddles on the concrete floors of all upper levels and basement
icon  Water storage drums, tanks and containers.
icon  Bulk waste containers
icon  Trenches
icon  Lift wells
icon  Safety barriers
icon  Rooftop and water tanks
icon  Treatment plants

Any other water-bearing receptacles.

Application of Insecticide:


Apply insecticides or anti-mosquito oils to all stagnant water and water-bearing receptacles at ground level and in upper floors weekly. Repeat application after a rain as the insecticide or oil will be washed off by the rain.
icon  Destruction of Mosquito Breeding
icon  Destroy all mosquito breeding found during the inspection and remove or treat all potential breeding habitats with insecticide.
icon  Report to the construction site supervisor all the breeding detected and the potential breeding habitats observed so that appropriate interim or permanent measures can be taken to eliminate the potential breeding grounds.
icon  Fogging
icon  It is not mandatory to conduct fogging at construction sites.
icon  Fogging treatment should only be done when there is a mosquito nuisance problem or disease outbreak.
Residual Spraying
icon  Carry out residual spraying of the interior and exterior walls of site offices and bangsals (if the construction site is located in a malaria-sensitive area or as instructed by NEA).

Biological Mosquito Control:

bacillus-thuringiensis-israelensis-bti“Bti”, Bacillus thuringiensis ssp. israelensis, are bacteria which infect and kill mosquito larvae. These bacteria are highly selective, killing only mosquitoes and their close relatives like gnats and blackflies. Formulations of Bti will only kill these types of insects and do not harm other kinds of insects, fish, birds, worms or mammals. Our Bti products include the Mosquito Bites, Mosquito Dunks, and Aquabac®.

icon  Bti is harmless to other wildlife and approved by NEA
icon  Easy to apply.
icon  Effective within 24 hours.
icon  May be applied as preventive measures

When Bti are eaten by the mosquito larvae, they damage the gut cells and quickly paralyze them, then kill the larvae quickly and efficiently. A moderate to heavy dose has been shown to reduce the mosquito population by one half in 15 minutes and the rest within one hour.
