Limit pesticide treatment on lawns to the problem area and a few feet beyond. Insect predators and other natural controls will survive in the untreated areas, repopulate the problem area, and slow down or control future pest outbreaks. Use Biorationals Biorationals are the safest pesticides for the environment and people. Bt is a disease that infects and controls the caterpillars. Biorationals effectively control plant pests and are less toxic to beneficial organisms.
Resistance is also less of a problem with biorationals.
Keep Simple Records and Evaluate Control Actions Keep records of pest problems and control measures. These can be as simple as notations on a calendar. Reviewing past calendars will help you predict potential pest problems. It is also very important to evaluate the effectiveness of pest control measures taken. This helps one learn which methods are most successful.
