Certainly, being the most common insect found in Québec lawns, the chinch bug is considered as an important lawn pest.
The chinch bug :
The chinch bug is a little insect that we can find in dry and sunny areas. It lives on the surface of your grass and it feeds on the sap of the lawn, resulting in leaving dry and brownish grass.
There are five chinch bug development steps before it becomes an adult. It is at the nymph phase that they cause the most damages.
What does it look like ?
When it’s still a nymphe, the chinch bug is red with a white strap on its back. As adults, it measures 3/16 inches long. It is flat with white wings on its back.
How does it reproduce ?
Chinch bugs survive winter as adults in turf thatch. In spring, they feed and they mate. A couple of weeks later, females lay up to 170 eggs, at the bottom of the lawn. Nymphs only take 4-6 weeks to become adults and it’s during this transition phase that they are the most devastating for your grass.
How to get rid of them ?
If your lawn is infested with chinch bugs, you must act and quickly! If you’re not doing anything, adults will soon attack your trees, your hedges, your plants… In spring, they will mate and your lawn will be twice more infested the following summer.
