How to get rid of Grub ?


What to Grub
 You can fool grub worms as a type of worm. But, in fact, they are the larval stage of certain beetles as the Japanese beetle, Oriental beetle, Asiatic garden beetle, adult beetles etc wander in the garden and feed on plants during the early summer. Around July and August, these insects lay their eggs deep in the earth, in the wetlands of the lawn and garden. In a few weeks, the eggs hatch and develop into larvae and larvae are called grub worms. They are plump little worm-like creatures that sport a C-shaped body with a red head and dark back. Grass grub worms feed voraciously on roots and in the process can damage the lawn. Similarly, they feed on the roots of garden plants, causing their death. Even though, they begin to feed as soon as they hatch, grub worms reach their full size in a month and those of this stage would be the source of potential harm to the plants.

Before the advent of winter, they move deep into the soil to hibernate and pupate in May. They emerge as beetles in early summer. Some of these larvae can emerge in spring and feed for a while before pupation stage. But this time, the power is not to cause great harm to plants. The presence of worms in the headless lawn or garden can attract skunks, raccoons, armadillos, moles, etc. These animals can dig in the lawn and garden, while seeking to grub they devour.

How to get rid of Grub
 While grub worms in small numbers may not happen much harm to your garden plants or grass, in large numbers, they can be a serious threat. It has been observed that regular watering, mowing and fertilizing normal can prevent possible damage that may be caused by worms headless. But if a square foot of soil in the lawn or garden has more than five grub worms, then we must seek measures to get rid of them. Even though there are different types of pesticides that can be used to eliminate them, it will always be better to try natural methods of fight against pests, as a first line of defense. If the infestation is not so great, then try to attract predators to grub, like the birds (blackbirds). Try frequent watering, so that the grass recovers lost root.

  1. While, grub worms in small numbers may not case much harm to your garden plants or grass, in large numbers they can be a serious threat. It has been observed that regular watering, mowing and normal fertilizing can prevent the possible damage that can be caused by grub worms. But, if a square foot of the soil in the lawn or garden has more than five grub worms, then, you have to search for some measures to get rid of them. Even though, there are various types of pesticides that can be used for eliminating them, it will be always better to try natural pest control methods, as a first line of defense. If the infestation is not that large, then try to attract predators of grub worms, like, birds (robins). Try frequent watering, so that the grass recovers from root loss.

    Another method is to get some nematodes from the garden store and mix them in water and spray it on the garden soil or lawn. Beneficial nematodes are microscopic worms that can enter the body of certain insects and their larvae and kill them. These nematodes enter the body of the host and kill the later within two days. However, they need moist soil to travel deep and so, water the soil thoroughly, before and after applying nematodes. But, this method is said to be more beneficial, when the larvae are small in size. So, the best season for using beneficial nematodes is July end or early August.

    You may also resort to application of milky spores (a bacterium that can cause milky spore disease in grub worms) on lawn grass. These spores affect the grub worms that feed on the grass and eventually kill them. Nowadays, commercial products for grub worm prevention are also available in the market. You have to apply them during summer, to prevent these pests. You may also prepare a pesticide by adding two cups of antiseptic mouthwash (without flavor), two cups of plain liquid soap, two cups of chewing tobacco juice (can be made by boiling chewing tobacco with water) and a cup of household ammonia, to a gallon of boiling water. Once cool, this mixture can be sprayed on the soil/grass, so as to get rid of grub worms.
