It is available at drug stores and organic gardening supply outlets. Triple rinse empty containers of liquid pesticides and pour the rinse water into your sprayer for use next time. Wrap the rinsed container in newspaper and throw it out with your garbage. Mow high, mow often and make sure the lawnmower blades are sharp. Keeping your grass a bit long will produce stronger, healthier grass with deeper roots and fewer pest problems.
Grass adjusts better to frequent rather than infrequent mowing.
The rule of thumb is to mow often enough that you never cut more than one-third of the height of the grass blades. When you mow this way, you can leave the clippings on the lawn, returning valuable nutrients to the soil. Try less toxic alternatives such as pyrethrums and pyrethrins, natural insecticides derived from chrysanthemums. They are used for ants, aphids, beetles, caterpillars, roaches, fleas, flies, leafhoppers, mosquitoes and ticks. Pyrethrums and pyrethrins can be found in powders and sprays as well as in flea and tick products for pets.
