you know a good solution for the invasion of woodlice? They are
constantly with us and munch our leaves and blooms.
generally don't affect leaves and flowers. They tend to feed more
on decaying plant material in the soil or, at worst ,eat seedlings
and roots. Earwigs are much more likely to damage buds, leaves,
fruit and flowers.
However, control methods
are much the same for both. You can reduce their numbers by clearing
up rubbish and plant debris from the area, leaving fewer places
in which they can hide and breed. Set traps of rolled-up newspaper
in which they'll shelter, and every three days or so shake them
out of the traps into hot water or step on them.
For earwigs, you could
spray the affected plants in the evening with a contact insecticide
like Baythroid Aerosol or Carbaryl. For woodlice, you could drench
the soil in the area where they seem to be prevalent with Diazinon
solution or sprinkle Diazinon granules. Or you could mix up a bait
of 15ml liquid Malathion concentrate with 100g of bran plus 100g
dried blood or blood and bone. Mix with a little water to moisten
and in the evening place small amounts of bait under upturned containers
in the problem areas. For earwigs, add 50g of sugar to the mix.
Put bricks or other heavy weights on top of the bait covers to prevent
them blowing off and to keep small children from interfering with
