The amount of water your lawn takes, would determine its physical condition. Ideally, watering should neither be less nor excessive, thus enough water is recommended. 

A lawn that is short or over watered may cause lawn grasses to become unhealthy and this would attract pests. With that, you should allow the sprinkler to run gently so that the water sinks rather than running off.

However, pest infiltration is sometimes driven by time and climate, wherein pests become active at certain times of the year. Likewise, climate is the reason why pests swell. 

Experts believed that the lack of beneficial insects allows pests to thrive on the lawn. They have identified damsel bugs, ground beetles, lacewings, tachinid flies, and minute pirate bugs as best defenses against damaging ones.

Further, proper lawn management must be understood by homeowners as likewise crucial like indoor or outdoor pest control. After all, a well-maintained lawn adds to the ambiance of your house, while promoting a green environment.
