Lawn Pests
Worm
Casts
Allolobophora
species of earthworms are responsible for worm casts. These worms feed
on decaying vegetation in the soil and deposit their muddy excrement on
the lawn surface. They blunt mowers, smother suppressed growth, and cause
ideal germination sites for weeds. They also encourage lawn disease, and
attract mole populations.
But earthworms can
have a beneficial effect on the lawn also as their burrowing activity
can help the aerating and drainage on the lawn, also they can incorporate
organic matter into the soil.
We find that you have
to strike a balance here between removing the problem and causing another
one. I have products that will suppress this problem for a few months
over the worst period, October - February or can remove it completely
if required.
Moss
Probably
the most common problem, that customers complain about, or ask our opinion
on, is moss. Mosses are very simple plants, which with liverworts are
classified together as bryophates. Most are generally lowly plants, which
are not seen very easily. They are very common and occur in almost any
terrestrial environment where moisture is available. Mosses produce no
roots as such, but they do produce structures called rhizoids, which have
a purely anchoring function, with water and nutrients being absorbed via
the arial part of the plant.
There are approximately
600 species of moss in the UK, of which about 30 plus can occur in turf.
There are normally 2 major growth periods for moss during the year, autumn,
when spores are produced, and spring, when spores are produced, before
dying off.
Lawn doctor use a
moss killer that will last for up to a 3-month period, and also have the
experience and expertise to keep it away. If you have a major moss problem,
or a recurring moss problem, talk to me, and we will explain the best
remedy for returning your lawn back to full health.
Leather Jackets
The leatherjacket
is the larva of the crane fly, and is 30-40mm in length when fully grown.
The crane fly is on the wing between late July and early September. During
this time they can lay their eggs below the surface of the turf. The larvae
or (leather jackets) hatch 2-3 weeks later, when they start devouring
your turf grass roots and stem bases with biting mouthparts. The larvae
can then feed right through to the following June.
Damage is not obvious
until the springtime when the Leather jackets are growing fast. The first
visible signs of damage are seen as straw-coloured patches of turf, which
later become bare and can become invaded by weeds. Feeding birds are also
a good indication that leather jackets are present.
Dog Urine
Damage
Dogs can cause
real damage to a lawn when they urinate on it. Urine from a dog or bitch
can cause scorching of the turf. There are no simple answers and no magic
cures or products on the market that can provide a quick fix.
Apart from training
the dog to use one area of your garden with bark laid down, or keeping
the dog off the lawn completely there is little you can do. You will stand
little chance of weakening the problem by following the dog around with
a hose or bucket of water to weaken the impact
Moles
A mole population will wreak havoc on lawns, golf links, racecourses and farms. Moles also endanger racehorses and cattle, wreck farm machinery and damage your lawns. A ban on strychnine, the poison they use under licence has exacerbated the problem.
.
The Pest Control Association, have had complaints nation-wide about the population boom of Moles. Mole catchers have been inundated with calls but without poison they must resort to trapping, which is more costly.
Using traps on a large site takes hours because of the increased labour and travel time in laying traps and checking them every 48 hours. Homeowners can temporarily get rid of moles by putting mothballs down their holes or deploying inexpensive mole traps.
If you have tried to remove this problem from your lawn with little or no success then please contact me and I can put you in touch with our pest control specialist.
Chafer Grubs
The chafer grub is probably the most worrying insect that you can ever have in a domestic lawn. You can tell that you have chafer grubs by if:
You can pull the
turf up like a wig or roll the turf back like a carpet.
You have dead brown
turf areas?
You have birds
or other animals digging in your lawn?
If you can answer
yes to one of the above you probably have chafer grubs, and you need this
problem sorting sooner rather than later. Once the birds discover these
in your lawn, it's like ringing the dinner bell, and you will end up with
no lawn left in a short space of time.
The life cycle of
this pest can be quite long of up to two years, in the colder months from
October onwards they start to burrow deeper into the soil of up to 12
inches and go into hibernation, during this winter period they are harder
to kill with chemicals.
When the soil temperature
rises in the spring they again produce larvae for the next generation,
then moving closer to the surface again to destroy the roots of your grass.
There is really only
only legal way of removing Chafer Grubs, and that is by using a particular
pesticide. Many have also tried using Nematodes as an alternative to a
pesticide to deal with this problem. Nematodes find and kill insect by
releasing their own unique bacteria that infect the insects. They are
non harmful to humans or pets and these products are unrestricted in their
use because they are normally harmless to the environment - However, they
rarely work! and most revert to a pesticide to remove this problem.
