Lawn Grubs are insects that live in lawns. They cause damage to plants and their eggs hatch into larvae which feed on plant roots causing them to rot and die. Larger grubs can eat through the bark of trees, but smaller ones may only affect grass blades or small shrubs. The larvae grow up to 3 inches long and they’re called “Grubworms” because they look like tiny worms with legs. They have two pairs of wings and can fly away from danger.
The larvae burrow into the soil where they lay their eggs. When the eggs hatch, the grubs will pupate within a few days until they emerge as adults. Adults are very small (about 1/8 inch) and have no wings so they cannot fly away. Their main job is to feed on plant roots until they reach adulthood when they molt back into larval form to continue feeding on plants again.
They don’t usually attack humans unless they see one of our pets. If you do come across a grub, it’s best not to touch it since the larvae can be deadly if ingested. You could try wrapping a piece of paper around its body and throwing it away, but this won’t kill the grub. Instead, you’ll need to use natural methods to get rid of them.
How To Get Rid Of Lawn Grubs Naturally?
There are many ways in which you can get rid of grubs naturally. Most of them involve getting rid of the conditions that allow grubs to thrive in your yard. Grubs need consistent moisture and at least 40 degrees F to survive and grow. You can prevent infestation by taking steps to improve the drainage in your soil or aerating it to let excess moisture escape. You can also increase the amount of sunlight falling on your lawn by trimming trees or moving sprinklers around.
You can also get rid of grubs by attracting birds and other animals to your yard. This works because grubs are a great food source for birds, so the birds will stay if they know where to find them. You can also grow types of plants that are known to attract birds like berries or trees that produce a lot of nuts. A third option is to use natural pesticides which are becoming more popular as people realize their benefits.
