Have you seen a fine like web structure on your lawn recently? Well, it could be Spider Mites. In this blog, we take a look at what are spider mites are, common signs that they are present and how to remove them from your lawn.
What Are Spider Mites?
Spider Mites are native mites that are on average around 0.4mm long and, on close inspection can be seen by the naked eye. When present, they will usually stay on the underside of the leaf as this is where they will feed. These mites will usually feed around the vein of the leaf and will pierce the cell wall of the grass.
When there is an infestation of mites, this will often cause a bleached appearance to affected areas. These mites will also create a fine spider-like web. When large populations are present, the bleached grass and webbing will occur in a ring shape.
What Conditions Do Spider Mites Like?
Spider mites prefer hot and dry drought-like conditions. When hot and dry conditions are present, their lifecycle will speed up, and they can go from an egg to an egg-laying adult in as little as two weeks.
Spider Mite Lifecycle
Spider Mites have five stages in their lifecycle: egg, larva, protonymph, deutonymph, and adult. The newly hatched larva will only have six legs; once they are fully developed in their adult phase, they will have eight.
How to Deter Spider Mites
As Spider Mites prefer dry drought-like conditions, long and frequent irrigation can deter them. If you are concerned that they may be present, we recommend irrigating your lawn two to three times a week for around half an hour. This will help bring moisture back into the turf, helping to deter the mites.
