Everyone can do something to
encourage insects into their garden. Not all of the suggestions given
below will be possible in every garden; some are clearly only feasible
if you have a larger plot. However, many of these suggestions will
be possible, even with the tiniest of gardens. Appropriate food plants
in containers will help attract insects into the garden and small
piles of broken pots can help provide shelter. 
•
If you have a garden that is large enough for you to have a small
patch of “waste ground”, allow native wild plants to
grow. Nettles in your garden will support a number of butterfly
and moth species, but should be in full sun to attract butterflies.
• Nettles also support a range of
herbivorous insects that are attacked by predators, such as ladybirds
and hoverflies. Your nettle patch can be used to provide a reservoir
for natural enemies of pests in the rest of your garden. You can
cut it back to prevent it from taking over the patch and put the
cuttings into your compost bin.
•
Allow a section of your lawn to grow into a small meadow. Even a
very small section can be effective. Different grass species interspersed
with wild flowers such as ox-eye daisies can look beautiful and
will attract more insects into the garden. If you buy wild plants
or seeds, do make sure that they originate from the UK.
• Try to have some form of hedgerow
made from native plants such as the hawthorn or hazel under-planted
with native woodland plants such as the bluebell Endymion non-scriptus
and wood anenome Anemone nemerosa.
• Avoid planting hybrid cultivars,
especially those with double flowers, which are often sterile, and
therefore useless to nectar and pollen feeders.
•
Don’t trim your shrubs until later on in the summer. If you
allow some of the fallen leaves and cuttings to remain in a section
of the garden, you will provide useful shelter. Make small piles
from broken crocks and stones to provide shelter for ground beetles
and other nocturnal insects.
• Compost your rubbish rather than
dispose of it. This will cut down on your garden waste, provide
you with free compost and create a habitat for a variety of insects.
• Avoid using chemicals if another
control method will do. Be aware that you may also be killing the
natural predators that feed on the pests, such as ladybirds,
ground beetles, hoverflies and parasitoid wasps. If you must control
pests, look into buying biological alternatives such as parasitoids,
ladybirds, nematodes or microbial pesticides, which can be purchased
from garden centres.
• Try to live with pest insects and
not automatically kill them. As long as they are not totally ruining
your plant or crop, their presence may have no real impact.
• Encourage pest controllers such
as hedgehogs, slowworms, frogs, toads and spiders into your garden
by providing suitable habitats. You can purchase toad and hedgehog
houses in many garden centres or make your own.
•
If you don’t want to plant wild flowers, traditional cottage
garden plants such as lavender, Buddleia, wallflowers and cornflower
are ideal for nectar and pollen eating insects such as bees and
butterflies.
• Dig a pond! Ponds attract dragonflies
and damselflies (the Odonata) as well as other aquatic insects.
They
will also bring in frogs. Try and plant around the pond to provide
perching points and have floating vegetation at the sides for the
Odonata to lay eggs. If you really want to encourage aquatic insects
and other pond life, you may want to consider having a fish-free
pond. Fish will eat the eggs of frogs and many of the larvae of
aquatic insects.
