Chinch Bug in New Brunswick

Submitted on May 22, 2019

What is a Chinch Bug?

Chinch bugs are small insects that have reddish brown bodies in their young stages and mature into black and white coloured adults. In late spring, chinch bugs mate and lay their eggs in a hot dry location (often on south facing hillsides or bare areas that receive a lot of sunlight). The eggs hatch in early to mid-summer and the young chinch bugs (known as nymphs) begin feeding and start to do damage to the lawn.  Damage from chinch bugs looks very similar to drought conditions.  The grass turns yellow/brown.   If the homeowner ignores the problem or confuses it with drought, the patches get bigger as the insect matures and seeks food further afield. Chinch bugs can ruin a lawn in as little as 3 weeks if no control methods are taken. 

What Product Does Weed Man Use to Treat Chinch Bug?

Weed Man uses Arena Insecticide for control of chinch bugs.  Arena is a non-toxic insecticide that effectively controls a broad range of insects, including chinch bugs. It was developed for the golf industry and has been in wide use in North America for several years. Arena is safe for humans, pets and the environment. The active ingredient in this product is clothianidin, which is absorbed by the roots of turf for fast-acting insect control. Arena is approved for use on chinch bugs by the Pest Management Regulatory Authority branch of Health Canada, and under provincial pesticide rules.  New Brunswick’s rules limit the amount of pesticide that can be applied to a property and limit most treatments to targeted spot spraying.  In extreme cases of insect infestation, a special permit can be obtained from the New Brunswick Department of Environment to permit allow blanket spraying. 

How Does Weed Man Tackle Chinch Bug?

Our technicians are licensed and fully trained professionals. When our technicians do the application, they focus their attention on the high-risk areas where chinch bugs thrive – south facing slopes, high heat areas, areas of past chinch damage, and areas where chinch bugs are currently present and feeding.  At Weed Man we stand behind the work we do.  That is why we will provide a no charge re-application if our technician did not do the chinch bug application properly.  It is important to note, however, that it can sometimes take more than one application to fully control chinch bugs, if the infestation is severe enough.  If your infestation is severe, our expert staff will advise whether a second chinch bug application is necessary and the cost for doing so, or if other alternatives should be considered, such as overseeding to repair damaged areas.

My Lawn Already Has Chinch Bug Damage. What Can I Do?

Bare chinch damaged areas need attention; they will not recover on their own. If left, they will look unsightly and will be attractive to pests that like hot, dry bare areas, namely weeds!  Weed Man recommends overseeding these bare areas. There is no way to fully guarantee that chinch bugs will not come back but making conditions less attractive for them to feed will help combat them in the long run.
