Sod webworm is another of the caterpillar types which can infest and damage our home lawns. While they most often prefer cool season grass types such as Kentucky Bluegrass and Fescue, sod webworm can sometimes invade buffalo lawns too. Although we must say again, that the prevalence of sod webworm in warm season grass types is often very low.
Like the army worm, sod webworm is the product of a moth (this time its the Crambus moth) which lays its eggs on our turf at night time, and then flies away, leaving a massive pest problem for us to rectify within the coming weeks as the eggs begin to hatch into little caterpillars ready to devour our buffalo lawn at great speed.
Checking For Sod Webworm In Buffalo Grass
Again, just like the army worm, we should follow the similar, but slightly different processes of determining whether we have an infestation of sod webworm in our turf.
The easiest way to first suspect sod webworm is to check our lawns first thing early in the morning while dew is still present on the buffalo grass. Sod webworm will leave a silky substance across our turf during the night, and which can then be easily seen in the morning before the dew disappears.
If we've found the silky webs across our lawn in the morning, then the next step would be to take a powerful torch with us onto our lawn at night time, and then to look around the grass for signs of these little caterpillars munching away on our precious buffalo lawns. Take your time, and get down on hands and knees around the areas we saw with the webs in the morning, and they should be fairly easy to spot.
Sod webworm will be less than 2cm in length, and usually have a white body and a different coloured head, which will most often be a brown type of colour.
There is little point trying to check for moths of sod webworm, as making such an identification amongst other moth types would be near impossible for the average homeowner. The crambus moth will not damage the lawn.
Killing Sod Webworm In Buffalo Grass
Killing sod webworm in buffalo grass is the same as with army worm. We apply the pesticide to the lawn just before sunset so the webworm feeds on the pesticide as it feeds on the buffalo grass.
Once discovered, sod webworm should be treated with the greatest speed and at the highest priority possible, as an outbreak of this pest can very quickly devastate an entire buffalo lawn.
