A lawn that turns yellow, thins out, or appears unhealthy despite watering often hides a deeper issue: damaging lawn insects or invasive weeds.

At Entretien Quesnel, we provide targeted professional treatments for homeowners throughout the North Shore of Montreal, helping eliminate the problem at its source and strengthen your lawn for long-term health.

Chinch Bugs

The Insect That Silently Destroys Your Lawn

The hairy chinch bug (commonly called chinch bug) is very common in Eastern Canada and can cause significant lawn damage if left untreated.

It feeds directly on grass blades by extracting plant sap, which leads to:

Signs of Infestation

  • Yellow or brown patches

  • Grass that looks dry even after watering

  • Irregular areas that expand during hot summer periods

These symptoms are often mistaken for drought stress.

Activity Period

Late June to July (during hot weather)

Our Solution

  • Professional insecticide treatment applied directly to the lawn

  • 6 to 8 weeks of protection (depending on rainfall)

  • Fast intervention to limit further damage

⚠ Areas that are already dead will not recover on their own. Overseeding may be recommended following treatment to restore lawn density.

White Grubs

The Danger Beneath the Surface

White grubs attack the roots of your lawn, causing widespread weakening and thinning of the turf.

How to Identify Them

  • Yellow patches that lift easily from the soil

  • Spongy or soft-feeling turf

  • Increased animal activity (raccoons, skunks, birds) digging to feed

Often, it’s the holes caused by animals that make the damage most visible.

Preventive Treatment

  • Application recommended in June

  • Single seasonal application

  • Protection throughout the summer

Crabgrass & Weeds

Professional Control of Invasive Plants

Some weeds are easy to spot and identify, such as dandelions or clover. Others, like crabgrass, are more deceptive and can quickly spread throughout your lawn.

Common Lawn Weeds

We commonly treat:

  • Dandelion

  • Clover

  • Plantain

  • Quackgrass

  • Ground ivy

  • Crabgrass

  • Wild violet

These weeds gradually reduce lawn density and create bare areas where other unwanted plants can establish.

Without proper intervention, their spread can accelerate from one season to the next.

Professional control not only eliminates weeds but also strengthens your lawn to prevent their return.

Crabgrass: A Special Case

Unlike most broadleaf weeds, crabgrass is a grassy weed — just like your lawn — which makes it particularly resilient.

It:

  • Blends in during the spring

  • Grows aggressively in hot weather

  • Can overtake the lawn if left untreated

A targeted and specialized treatment is necessary to eliminate it effectively.

Why Professional Treatment Is Essential

Our treatments:

  • Are applied in a targeted manner

  • Comply with current regulations

  • Are handled by trained professionals

Depending on weed density, temporary browning may appear for approximately 3 to 4 weeks.

Overseeding is often recommended to strengthen the lawn and prevent future invasions.

Our objective is not just short-term greening, but long-term lawn health — building density, resilience, and natural resistance to insects and invasive weeds.

The Best Prevention: A Dense Lawn

A thin lawn leaves more room for weeds and insects.
A dense lawn:

  • Naturally suppresses weeds

  • Better withstands climate stress

  • Becomes less vulnerable to white grubs and chinch bugs

💬 Our program works like a health plan for your lawn. Results build progressively throughout the season.
