Insects & Bugs
Common Lawn Insect Problems:
Over the years, insects have gotten a bad
rap and it seems like whenever we see one of these little guys we run for a can
of bug spray and try to kill everything that moves in the lawn.
Some insects can do substantial damage to a lawn, but unless you see that type
of problem, it is better to let Mother Nature run the show.
Axent Green has the training and knowledge to identify specific insects that can
damage a lawn. Only then do we apply treatments to control these harmful
insects. We can also apply special controls to reduce fleas and ticks in the
lawn to help protect your family and pets from these disease carrying insects.
are the larval stage of
many different beetles, including the Japanese beetle, especially in
Western Montana. The grub lives below ground and feeds on the roots of
tender grass plants that soon kills the plant. They are most destructive
mid to late summer, but the damage they cause may not show up until
early fall and by then, it's too late.
The best time to control grubs is in early summer, just after they
hatch. At this time they are very susceptible to treatment and just
before they start causing extensive damage to your lawn. Our grub proof
treatment will control grubs in your lawn before they can damage your
Sod Webworms can be a problem for some homeowners in
western Montana. If lots of sod webworm moths are observed in the
evening, watch for damage in about 10 to 14 days. This is when their
eggs begin to hatch into caterpillars. These caterpillars chew off the
grass blades close to the soil surface leaving brown stubble as damage.
Early August is typically when we see the heaviest damage, although
sometimes damage is also heavy in June. If sod webworms are present in
your lawn we will treat for them.
Montana has had some severe outbreaks of tick
infestations. Several kinds of ticks infest lawns. They drop on the
grass from dogs, rodents (includng squirrels) and even some birds. Most
ticks will attach themselves to people and pets if given the
opportunity. Pain main result from their bites. Some ticks transmit
diseases, including Rocky Mountain Spotted Fever, Human Monocytic
Ehrlichiosis, Lyme Disease and tularemia. Even though ticks won't cause
any damage to the lawn, it is important that if you have heavy tick
infestations in your area that steps be taken to control them.
What You Should Know
Billbugs are weevils or snout beetles that that rarely fly.
Billbugs eat turf grass roots just below the thatch layer.
Heavy billbug infestations can kill grass, with peak turf grass
injury occurring in mid to late summer
Early billbug detection is important for the prevention of
widespread turf grass damage
Keeping turf grass properly irrigated and fertilized will
minimize potential billbug damage
Billbugs can be a serious turf grass pest throughout the entire U.S.,
with at least eight species known to occur. Although not a new pest to
turf grass, billbugs are often ignored or misdiagnosed, and root decline
is confused with drought stress, fungal disease, or other insects. In
most cases, damage is diagnosed as dollar spot disease or white grub
feeding. Newly laid sod should be carefully monitored for the presence
Billbug larvae are the damaging life stage. The greatest injury to turf
grass usually appears from mid-June through late July, although billbugs
can be feeding all summer. Turf grass will look drought stressed with
small brown patches appearing. If left un-treated, billbugs will
eventually consume the roots and destroy the entire root system.
Blades of grass can easily be pulled away from the crown with billbug
infestation. Sawdust-like frass indicates billbugs even if you do not
see larvae feeding.

treatment plan for eliminating Billbugs from your lawn.
