Black beetle can be a problem for owners of all lawn types, including buffalo grass lawns. A native of Africa, the black beetle goes through various life stages, each of which can cause at least some damage to our lawns. But with this possible damage also comes benefits too.
In every case I have ever been asked if Black Beetle was damaging a lawn, it has never once been found to be true. Indeed these lawns often can have black lawn beetle, which can be very common, but the responsibility of poor lawn health lay not with the black beetle, but with the lawn owner themselves.
In all these cases the lawn owner wasn't keeping their lawn care up to scratch, and then went looking for a culprit to blame for the lawn not looking its best. And the most common culprit of all is the common black lawn beetle.
The fact is that a buffalo lawn would need to be very heavily infested with beetles for any damage to be seen at all, and the truth is that most lawns will only ever have very small numbers of these beetles, incapable of doing damage.
Besides this, at the times of year when the beetle is most actively chewing on the roots of our lawn, our lawn is growing at its maximum speed and health, and will very quickly repair any minor damage, often without the lawn owner ever noticing. And once our lawns go dormant over the colder months, so too do black lawn beetles.
Black beetles in lawns can in fact be of great benefit to lawns, as they burrow through the soil, they're actually doing a wonderful job of naturally aerating the soil for us, and this can be a wonderful benefit for our buffalo turf.
How To Kill Black Lawn Beetle In Buffalo Grass
Lawn beetle is very easily killed in buffalo grass by the use of simple pesticide dusts which are commonly available for a small price. The dust is applied to the lawn and watered in. The pesticide works its way through the soil, killing the black beetles as a result.
However, before doing this, we would recommend rethinking this approach, and would encourage the lawn owner not to proceed with treating black lawn beetle. Black beetle do provide benefits to the lawn soil, they do very minor damage which in most cases will never be noticed, and in most cases we're simply pouring pesticides into the environment for no benefit, or in fact… loss of benefit.
Having said that, Black Lawn Beetle should be treated in buffalo grass, and all other lawn types at any time they can be seen to be growing into large numbers, at which time they can indeed overrun a lawn and cause damage, though such cases will be rare.
