Top 8 list of lawn and garden pests

Here are 8 of those you should be concerned with if you want to have a beautiful lawn and a lush garden.

1. Aphids


Aphids are tiny, soft-bodied, pear-shaped insects. They can be green, brown, yellow, red or black. They live on a vast variety of plant species and they can be found on roots, bark, stems, leaves and fruit. They feed on the sap of plants, which causes the leaves to distort and fall.

2. Caterpillars


A caterpillar is a soft larva, and as soon as it hatches, its ultimate goal is to eat. Caterpillars are herbivores and feed on the host plants they choose as a buffet. They chew on and destroy the leaves and stems, and they also dig tunnels in fruits. The bigger a caterpillar gets, the more food it needs. 

3. Slugs and snails

Slugs and snails

These voracious eaters have chosen lawns and gardens as a buffet, as they are generally well irrigated or watered. They especially like gardens because they provide shelter from the sun as well as tender leaves to feed on. These little nocturnal critters can't resist newly germinated seeds and they won't hesitate to destroy them.  

4. Beetles


Beetles have the ability to jump like fleas. The larvae feed on plant roots whereas adults create numerous small, rounded holes in leaves. 

5. Thrips


Thrips are tiny, flat-bodied insects that parasitize many plants. They are 1 to 2 mm in length and bite plants to feed on their chlorophyll. The affected parts of plants turn grey or white or simply become discoloured. Generally, plants with thin leaves or petals are a target.  

6. Japanese beetles

Japanese Beetles

The larvae of Japanese beetles are commonly called "white grubs". They are a real affliction for lawns, as they feed on grass roots, and are one of the most destructive lawn insects in Canada. The presence of Japanese beetle larvae attracts raccoons, skunks and birds, which then damage the lawn while digging up their meal. 

Adults attack over 250 plant species by feeding on the leaves and flowers. 

7. Cutworms


Biologically speaking, cutworms are actually caterpillars. They transform into moths once they reach the adult stage. There are two types of cutworms: those that feed on leaves, flowers and fruits, and those that live on the ground. The first type creates small, irregular holes or cuts in plants, while the second feeds on young stems and roots, which often causes the plants to die. 

8. Sod webworms

Sod Webworms

Sod webworms are among the most attracted to lawns. At the larval stage, they feed on the base of grass leaves and stems, which kills the grass. These insects are rarely seen during the day; they hide and only come out at night. When they reach adulthood, they turn into small moths and no longer damage lawns.
