In vineries one of the best ways of destroying these
creatures is to paint the hot water pipes with one part of fresh lime
and two parts of flowers of sulphur mixed into a paint. If a flue is
painted in this way, great care should be taken that the sulphur does
not burn, or much damage may be done, as the flues may become much
hotter than hot water pipes. During the earlier stages of growth keep
the atmosphere moist and impregnated with ammonia by a layer of fresh
stable litter, or by painting the hot water pipes with guano made into
a paint, as long as the air in the house is kept moist there is not
much danger of a bad attack. As soon as the leaves are off, the canes
should be dressed with the recipe already given for painting the
walls, and two inches or so of the surface soil removed and replaced
with fresh and all the wood and iron work of the house well scrubbed.
If carnations are attacked, tying up some flowers of sulphur in a
muslin bag and sulphuring the plants liberally, and washing them well
in three days' time has been recommended.
Tobacco water and tobacco smoke will also kill these pests, but as
neither tobacco nor sulphuring the hot water pipes can always be
resorted to with safety in houses, by far the better way is to keep a
sharp look out for this pest, and as soon as a plant is found to be
attacked to at once clean it with an insecticide which it is known the
plant will bear, and by this means prevent other plants from being
infested.
