Lawn Care Problems and Pests? The most likely culprit is the grub, but how can you tell? Grubs are made up of larvae from beetles and chafer’s. They are a white colour and they consume the roots of the grass plant that make up your lawn.
The grub affects your lawn by causing irregular patches of dead grass in the early spring and then again in late summer to early fall. Why is there presence so noticeable in the spring and late summer? Well this is due to life cycle of these grubs and knowing this cycle is the best way to kill these pests in your lawn.
First to find out how serious the grub problem in your lawn is there is a simple test to you can do. All that needs to be done is to cut a 1 foot square section of your lawn with a spade and turn the lawn section over in one piece and count the numbers of grubs present in this area.
If the number exceeds 5 grubs then you have a grub problem. A sure sign that you need to consider treating your lawn for grubs if you notice “grub eaters” such raccoons and skunks digging up your lawn in search of these tasty pests.
Another indication that the grubs are hurting your lawn is a change in the colour and feel of your lawn when you walk on it. A lawn where grubs are at the problem stage will turn the lawn much yellow-er than the normal green as well as causing the lawn to feel soft and bouncy when stepped on.
Upon determining that there is indeed a pest problem, realizing that the grub life cycle is very predictable and properly timed pest control treatments become very important in slowing and stopping these ravenous insects.
A grub’s life cycle is summed up as follows; at the end of June and early July adult Japanese beetles come out of the ground searching for food and mates. Upon mating female beetles lay eggs over the course of few weeks later in July. These eggs (normally 50 or more) are laid in the soil of your lawn. As long as the conditions are right then eggs will hatch within a couple of weeks.
Feeding begins right away and lasts throughout August. While these grubs are young and are eating near the surface they are most susceptible to insect control methods. This is the best time to halt this years growing population of pests in the lawn. From the end of August until mid-October these continue to grow and eat. It is this reason that you may notice increased damage to the lawn during the fall months.
In autumn temperatures fall and these pests burrow further down in to the soil where they winter safely below the layer where the ground freezes. Spring arrives and the ground begins to warm again, the grubs crawl up towards the root layer of your lawn to feed for short length of time before they turn into what as known as pupae.
During this stage they are resistant to any type of insecticide. The grubs then lye dormant until the end of June, thus completing the grub cycle of life.
Grubs are a key issue in lawn care problems and pests
In order to make sure that the grub insecticide can work properly it must be able to reach the soil layer of your lawn. If there is too much thatch built up on your lawn the insecticide will be unable to reach the level where the grubs are rendering the grub control useless. If the thatch is compacted or thicker than the width of your finger nail there is little chance of the grub treatment getting down to where the grubs are feeding.
Detaching the area before any application must be done. Henceforth, keep the amount of thatch on your lawn to a minimum. By doing so you will help to lessen the numbers of grubs present in your lawn as well allowing ongoing grub treatments to reach the soil layer where these pests are present.
The best and most effective time to apply any grub control is during the point in the life cycle when the grubs are near the top of the soil layer and are actively feeding (approx. late July to September). These pests will consume much more of the grub killer upon hatching as well as it takes much less grub killer to kill small grubs than adult ones.
When dealing with Lawn Care Problems and Pests it is best to apply the Grub Control when you notice Japanese beetles flying near where you reside. The Grub killer has a residual effect that lasts for up to 4 months so be sure not to apply it too early in grubs life cycle.
Water the lawn a day prior to applying the grub killer, and then apply the grub control when the lawn is dry. A watering of the lawn after the application must be done to dissolve the pesticide down into the root layer where the grubs are eating your lawns’ roots.
