The reason that I first acquired my carnivorous plants was to keep the flies under control in the limery – a natural solution that is also fascinating. The pitcher plants, which featured in last week’s Three Things Thursday are good for controlling large flies, but when it comes to fruit flies and little black compost flies, you need a sundew or two.
The most common and easiest to grow in a UK conservatory is probably the Cape Sundew (Drosera capensis). The plants have linear leaves and either pink or white flowers, the former associated with leaves with red highlights. Mine are always covered in little flies:
And then, if you’ve got some hanging space that’s high enough so you won’t walk into it (and honestly, you really don’t want a face full of this), there’s my favourite – Drosera dicotoma, the leaves of which can reach 30cm. Mine had a bit of a set-back earlier in the year when I was on holiday, but has now grown some new fresh leaves which haven’t had much time to catch many flies, although it is capable of snaring big ones.
So, who needs chemicals or fly paper, when nature can solve the problem for you?
