Four Tips for Pest Control on Green Roofs

Your green roof is an incredible engineering feat that provides insulation and stormwater management, but could its lush greenery be putting you at risk for an invasion of pests?

Vegetated roofs are often touted as a way to encourage biodiversity, but that isn’t limited to the plant selection. Whether your roof has low grass, flowers, shrubs, or food gardens, insects and animals will inevitably be attracted to the foliage.

Integrated pest management can help you stay ahead of pest activity and ensure any infestations are treated in an environmentally sensitive manner. Follow these tips to ensure your roof will thrive without becoming overrun with wildlife.

1) Understand Which Pests Frequent Vegetated Roofs: Animals need three things to survive – food, water, and shelter – so it’s no surprise that a manicured green roof can provide these in abundance.
“Green roofs are living architecture,” explains Pat Copps, a board certified entomologist and technical services manager for Orkin. “As soon as you start putting plants up there, pests will start moving in.”
Pests run the gamut from those that are attracted to ornamental plants to ones that thrive in urban areas:
  • Insects such as ants (fire or carpenter), spiders, hornets and wasps, and silverfish are typically the biggest group of unwanted guests.
  • Birds, mice and rats, and even nocturnal creatures such as raccoons and possums may become an issue.
  • Mosquitoes can create a problem, particularly if there is ponding water for them to lay eggs in.
  • Large cockroach species often thrive in heavily mulched areas,” notes Judy Black, a board certified entomologist for the pest management firm Steritech. “Occasional invaders such as earwigs may also be brought in on potting soil, and ground beetles may be initially attracted to lights at night and then take up residence in soil and mulch.”
  • Termites are less common but not unheard of, adds Paul Curtis, a board certified entomologist and entomology and regulatory services with Terminix Commercial.
Because your roof is designed to be a habitat, keep in mind that one pest problem usually encourages another. For example, birds may become more attracted to the area because there are better nesting opportunities and a greater amount of insects to eat. In turn, feathered friends may be carrying mites that will then establish a population on your roof. It’s the circle of life, but it can be managed so it doesn’t get out of hand.

OED Lighting

Both technologies are classified as solid-state lighting, a type of lighting system that relies on semiconductors that convert electricity into light rather than filaments or gases encased in glass bulbs. However, the similarities end there. Differences in the materials and manufacturing processes used to make the two light sources lead to differing characteristics in the finished products.

“One of the main distinguishing characteristics of an LED is that it’s a point source, which makes it a good choice for directional applications. However, if you were to look directly at the diodes, they’re extremely bright – maybe up to 1 million candelas per square meter,” explains Jeannine Wang, director of business development for Acuity Brands’ OLED Business Group. “In order to be able to use the light in a useful fashion, glare control is a big consideration. You need optics to control the light from an LED source.”

LED Lighting
 OLEDs, on the other hand, are thin sheets (less than 2 mm thick). Light is produced by the whole sheet instead of by a diode, but the light is less bright than that of an LED, so it’s comfortable to view directly without the aid of a diffuser or other optics.

OLED Lighting
The thinness of the finished product is increasingly leading manufacturers to high-end architectural fixtures and task lights – in other words, “following the same path LED did before it,” says Ethan Biery, LED engineering leader for Lutron.

Lifetimes for OLED haven’t quite caught up to LED (30,000-40,000 hours vs. 50,000-plus for LEDs), but they’re moving in the right direction. “OLED technology is still several years behind regular LEDs, so a lot of the things people are struggling with now were solved for LEDs years ago,” Biery adds. “However, the technology is rapidly improving. A lot of that has to do with the DOE – they’re pouring research and development dollars into incentivizing manufacturers to invest in better technologies and equipment. OLEDs are still a few years out from mass commercial adoption, but you can already find some residential OLED fixtures in Home Depot.”

Green, sustainable, circular...?

Circular Buildings

The choice is yours. And if you wish, there are many more building qualifications worthwhile to strive for. We got used to ‘energy-efficient’, ‘green’ and ‘sustainable’ buildings over the past years, but ‘circular’ is the new buzz word also getting political attention, while ‘resource-efficiency’ comes in from the European Commission.

Whatever the name, buildings have a huge potential to contribute positive to solve New York, New Jersey and Connecticut challenges of today. The bunch of – all valuable – sustainability qualifications shows that the only meaningful way to handle this is to take an integrated (‘holistic’) approach. Buildings contribute to the major environmental problems of our time, but the same buildings also offer the solution.  

Safe and sustainable buildings: the future is now
We can already make our buildings more sustainable today. By energy efficient renovation, by building resilience and fire safety into the building envelope, by providing people a quiet and healthy living environment, by avoiding the use of scarce resources and enhancing reuse and recycling of buildings and its components. We believe in such an integrated approach as also shown in the illustration below developed for ROCKWOOL. And not only we believe this is the right way – several building rating schemes apply a similar multi-criteria assessment.

We’ve gained a reputation as a premier service provider in the industry, and have developed a solid reputation for creating innovative building management and energy performance solutions. This includes retrofits and replacements of older, less efficient systems with newer, high efficiency systems. Additional, our on site management and engineering staff have the experience to operate and maintain all types of mechanical systems, including Package units, Chiller/Boiler Plants and Absorbers.

Floor Finishes: Costs and Effectiveness


The demand for hard flooring, especially vinyl and various types of decorative tile, will rise by 5 percent each year to reach 9.3 billion square feet by 2017, according to Freedonia, an international market research firm based in Cleveland, OH, The study, conducted in 2013, reflects a fairly significant rebound driven by new building construction and renovation since the economic downturn in 2008.

It also reflects what many jansan distributors and building service contractors (BSCs) are well aware of, which is "The office and commercial segment will post the strongest growth during this time, fueled by double-digit advances in construction spending and rising interest in hard surface flooring as a low-maintenance alternative to carpeting."

According to the report, a great deal of the hard flooring selected will be luxury vinyl tile flooring (LVT), favored because it offers the durability and performance properties of traditional vinyl flooring products, but which features a high-gloss appearance.

"Many retailers, including major chain grocery stores and pharmacies, are installing LVT floors," says Michael Schaffer, a senior executive with Tacony's Commercial Floor Care division and president of floor care equipment manufacturer Tornado Industries. "They like LVT because it typically is a nowax/nofinish floor, making it easier to maintain. This helps reduce floor care costs and environmental issues often associated with more traditional vinyl composite tile floors (VCT)." 
After taking the trouble to select the floor finish that delivers the most mileage and that is the least labor intensive to apply, maintain, and strip, selecting a less-than-satisfactory floor machine would totally defeat our overall goal of making floor care more cost effective.

"One of the wisest investments a facility service provider can make—and a distributor can help guide and implement for their customers—is to select 'best in class' floor care equipment," Schaffer says.
