It's Chinch Bug Season In Canada!

Summertime! And the living's easy... when there's no chinch bug interactions, that is. 

it's no secret that chinch bugs are most active in the summer months when hot and dry temperatures persist across Canada. They live in the thatch layer of home lawns, where they feed on the grass and suck out plant juice to their hearts content. When chinch bugs feed, they release enzymes that facilitate easy feeding, which continue damaging the plant after feeding, and cause the grass to turn brown and potentially die. Not great, lawn lovers!

Chinch bugs are generally found in hot, sunny areas of a lawn. They tend to aggregate and work in groups, which results in localized dead patches at the start of the chinch bug reign. These dead areas are brown, irregular sunken patches, which can coalesce into larger dead areas. Damage generally becomes evident in July and August when temperatures get hot and drought conditions become more prevalent, making this prime chinch bug season. Opportune time for a blog, wouldn't you say?

We agree! Below you can find our tried and tested tips for chinch bug prevention and recovery.

Water Your Lawn As Needed 

Since this pest requires hot dry conditions for optimum survival and reproduction, irrigation during spring and early summer may increase the incidence of pathogen spread, especially the lethal fungus, Beauveria spp. The adults can withstand water because of the protective hairs on the body but the nymphs readily get wet and can be damaged by large water droplets.

Use Pest Control

Chinch bugs are rather easy to detect in turf and targeted insecticide applications can be applied to reduce populations which appear to be building to damaging levels.

Talk to your local Nutri-Lawn about Integrated Pest Management principles effective for controlling chinch bugs.

Use Resistant Turfgrasses

Overseed areas that have historically been damaged by chinch bugs with perennial ryegrasses, fine fescues and tall fescues that contain entophytic fungi. Endophytic grasses deter chinch bug feeding.

What Recovery Looks Like

Slightly damaged turf will recover rather quickly if lightly fertilized and watered regularly. Heavily infested lawns may have significant plant mortality because of the toxic effect of chinch bug saliva and reseeding will be necessary, unfortunately.

Major damage caused by chinch bugs is often mistaken for drought stress and not treated accordingly. It's important to identify, treat and eliminate chinch bug infestations before they multiply and chinch bug damage becomes extensive to a lawn.

Sure, chinch bugs may be small in stature, but they can cause major damage to your lawn if left untreated. The damaging nymphal life stage of the chinch bug is bright red in color with a white stripe across its back. In order to find them you will have to get down on your hands and knees and spread the turf apart. The best place to look for active chinch bugs is in areas where the stressed turf meets the healthy turf.
