Try to use organic gardening principles instead of pesticides on your property and talk to your neighbours about doing the same. Some pesticides have been implicated in triggering asthma. If you suffer from airborne allergies, the rules are the same as they are in the spring:

• Keep windows and doors closed, control indoor humidity by using air conditioning and/or a dehumidifier, and avoid going outdoors before 10:00 a.m. as pollen counts are at their peak in the morning hours.
• Remove your shoes at the entrance to your home to avoid tracking in pollen, moulds and pesticides.
• Shower or bathe before going to bed and wash your bed linens weekly.
• Use a vacuum with a HEPA filter and remember damp wiping and moping is best – no sweeping.
• To control dust, dust mites and other indoor pollutants, there are two words to remember – clean and dry.
• It is especially important to remove clothing and paper from the basement in the damp summer months. These items absorb moisture and can provide a starting point for mould growth.
