Your
green roof is
an incredible engineering feat that provides insulation and storm water
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:

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.
