Wild birds are natural and wonderful guests whenever we're lucky enough that they visit our homes and gardens. In fact, if we have birds visiting our gardens regularly, it's easy to say we've done something right in our gardens that these wild creatures would like to visit.
White Curl Grubs can be responsible for a lot of damage occurring to lawns when the grubs feed on the roots of the grass. The earliest damage will appear as patches of turf which seem to be dying off with an appearance of drying out of the leaf of the lawn. As the damage progresses and the area enlarges in size, the lawn will be able to be pulled up from the soil. This occurs as the lawn area is severed away from it's roots.
Cutworms get their name from their eating habit which involves chewing through the stems of lawns and plants, with the result being that the rest of the plant or blade of grass falls over.
Cutworm is another of many caterpillar varieties which can damage both lawns and gardens, other caterpillar pests include sod webworm and armyworm. Like these other lawn pests, Cutworms are nocturnal, feeding only at night, and hiding in the thatch layer and upper topsoil during the day.
Army worms are another type of lawn pest which are commonly referred to as lawn grubs. This caterpillar of the Spodoptera mauritia moth is most prevalent throughout the warmer months of the year, and repeat infestations can occur.
The damage caused by Army Worms is most obvious by the speed at which damage occurs, as the caterpillars form very large numbers and behave as a colony to eat away at the green leaf of lawns.
Army Worms can vary in colour from green to brown to black, they can reach a maximum length of about 4 cm, and will become plump as they feed and mature.
Sod webworms are a small green and brown caterpillar which feeds on the leaf blades of lawns, and will affect all lawn types. When fully grown, the sod webworm will reach a length of about 2 cm, will develop grey hairs over it's body which will eventually turn a tan colour, while it's head will often become orange.
Sod webworm will only feed at night during the growing season of lawns which is between Spring, through Summer and onto Autumn. Sod webworm will then hide in silk lined burrows during the daylight, helping them to avoid detection by people, escape the heat of the day, and to avoid being eaten by birds. Their burrows are usually located at the base of the lawn, usually at soil level or inside the lower thatch layer.
African Lawn Beetles, also know as Black Lawn Beetles are often held responsible for creating a massive amount of damage to lawns. Also, many times when lawns begin suffering damage or stress - the lawn beetle is again held responsible, regardless of whether a single beetle has been seen or not.
It is true that Black Lawn Beetle can cause severe damage in a lawn, but in real truth this is an extremely rare occurrence, and in practice when lawn owners do blame Black Beetle for lawn damage - it is in fact not the cause in well over 99% of cases.
