Moth Infestation in Lawn

[bigdog]

I have a Moth infestation in lawn, small white moths, dozens are hundreds.
What are these, and how do I eradicate them !

Webworm moths. They are laying larvae.

How close is the lawn to the lake?

Not close to the Lake at all, about 2 miles.......

Spectracide Triazicide for lawns.
You should be able to find it in any of the local supply stores.

If the lawn is sloped and you choose to use the dry rather than the concentrate, be careful when applied and watering in. Too much rain or heavy sprinkler action will wash it down the slope.

If you are using the concentrate, just avoid a windy day.

It should say that on the directions of each of the options.

The Winnipesaukee Basin extends far from the Big Lake--and surface flow eventually carries chemicals and their derivatives downhill to multiple lakes.

The larvae are something else's food: Usually birds (like Chickadees) eat the larvae (and adults) of butterflies and moths.

Speaking as one who has a "lawn" of ferns, Pink Lady Slipper, Jack-in-the-Box, Canadian Yew, Jewelweed, Blueberries and Queen Pine, is this really a problem?

If they were being eaten.
He would hardly notice the few that exist... as they exist everywhere.

The directions are pretty stringent on how and where to use.

Changing ground cover would be an excellent idea, but that has to be his decision.
