According to experts, the global crash in insect populations is on its way to our shores. Entomologists in Australia have recorded lower than average numbers of wild insects and this is a worldwide phenomenon.
The most alarming thing is that we don’t know why the populations are declining, it may be due to urbanisation, insecticide use, elimination of plants that form insect habits and food etc. Climate change and the rising sea level may also have something to do with it.
Whatever the cause, we need to ensure we protect insect populations because they play a vital role in environment.
By having insect screens installed around the home, we can safely keep them outdoors instead of using nasty insect sprays or traps to kill the already declining insect population.
