Lawn pests of all kinds can invade nearly any turf and cause extensive harm. This applies especially in certain climates, seasons or under turf-stress conditions. However, an invasion can be either prevented or remedied if you're careful.
Common Pests and How to Stop Them
Some types of insects are region-specific, but common invaders in North America include the following:
Ants
Ground-dwelling ants make deeply rooted nests in household lawns. Their presence might create unsightly mounds in turf and soft spots that can further erode into large depressions. Extensive ant colonies mean lots of tunnels and warrens, which can dry out your turf soil and brown out large patches of grass.
Treatment: You can fight many species of ants with periodic applications of insecticide, consistent lawn watering and, if certain colonies become deeply rooted, by hiring professional insect removal experts to destroy the nests.
Billbugs
There are several species of billbugs that commonly invade lawns and feed on the parts of grass where turf and roots meet. Female billbugs in particular are dangerous to turf because as they eat, they also leave behind larvae in their wake. These larvae are even more voracious than their parents and hatch rapidly in the warmer months to eat grass stems and shoots. A single female billbug can drop 200 or more eggs per season, meaning an obvious problem for your turf.
Treatment: For billbug treatment, a thorough application of insecticide during the early spring is the best remedy. This is a time of the year in which the female insects haven’t yet laid their seasonal eggs, so you’ll be stopping the problem before it gets worse.
Piercing-sucking Chinch Bugs
Chinch bugs slowly but steadily ruin turf by piercing grass shoots with their mouth parts and sucking out the juices. This can cause major brown patches when done by hundreds of these little critters at the same time. Populations can grow quickly as a single female can lay more than 200 eggs in heavy grass thatch over a couple of months.
Treatment: You can treat piercing-sucking Chinch bugs with an application of insecticide during the spring months and by making sure to keep the level of thatch in your lawn low enough to shrink their preferred lawn habitat.
General Prevention and Protection
The most important things you can do to protect your lawn are preventative steps that keep it healthy. Good year-round lawn maintenance creates a turf landscape that’s unfriendly to voracious pests and leads to grass that’s resilient to attacks.
Some essential lawn care steps include the following:
- Water your lawn regularly and deeply during dry weather.
- Regular mowing of turf to a height of 3 inches or less.
- Avoid too much fertilizer use.
- Aerate soil at least twice a year, especially during moist spring and fall weather.
- Avoid thatch buildup with frequent raking and lawn cleaning.
Be vigilant and step into action to identify and destroy pests as soon as you notice their presence. A normally healthy lawn makes pest damage much easier to notice when it starts.
