No pesticides needed in my garden to tackle “pests”

After the cold April month with a predominantly Northern wind, I welcomed the warmer weather in May. We also had some much needed rain. Our weather is quite inconsistent these days with highs and lows. The cold spell has resulted in a high number of aphids.

Plants did not grow well and one may be tempted to spray against aphids but in my garden, I never use any chemicals whatsoever. Now, a few weeks later, most of the aphids are gone since their natural predators such as ladybirds have appeared and consumed the aphids. If you have enough diversity in your garden, there will be natural predators to deal with pests. Please bear in mind that aphids themselves are on the menu for so many species.

Harmonia axyridis is an invasive species from Asia and in my garden the most common ladybird i am afraid.

Another so-called pest in the garden is the spindle ermine, Yponomeuta cagnagella. Their only foodplant is the spindle, or Euonymus europaeus.  The moths are eaten by birds, spiders and bats. The caterpillars can envelop the plant in webbing and it looks unsighty. Ichneumonids or ichneumon wasps and birds feed on the larvae.

Again, no need to use pesticides and let nature do what it knows best. Fascinating to me is how a tiny moth was able to locate its foodplant among the thousands of shrubs in gardens. Amazing, isn’t it for such a small creature.
