Are the goose beetles swarming in your lawn?
You typically see ladybugs in your lawn from late May to mid-June, when they swarm around. If the lawn is warm and dry, it is the perfect environment for ladybugs to reproduce.
Although most eggs have already been laid by the time the goose beetles start swarming, you should set up a trap and thus make it difficult for the females to lay the rest of their eggs. Once the eggs are laid, it takes about 6 weeks before they hatch and you see small goose beetle larvae. These are goose beetle larvae that gnaw at the roots of the grass, so that all or part of the grass dies. If there are many larvae, you will typically experience that the grass lies loosely on top of the ground, as if it were a carpet on the grass that could be easily removed. The infestation can be so bad that you have to reseed bare spots or lay a new lawn.
With a goose beetle trap, you can reduce the number of adult goose beetles and learn more about when the swarming occurs and thus when you should control goose beetle larvae with nematodes.
Set up the goose beetle trap at the end of April so you can catch the goose beetles before they lay eggs in your lawn.
