We've received a lot of queries about the ultimate Fly and pest busters so here's a breakdown of which carnivorous plant is the most effective plant for particular pests.
Sarracenia (Trumpet pitcher plants)
The best fly and roach catchers around!!
Once each trumpet has a few pitchers and once each opens up, it is open for business!!
The plant itself will catch as many flies and insects as can fit into each pitcher, which can be as many as hundreds, per pitcher, per day; ergo the taller and wider each pitcher on the plant gets, the more pests it can fit in the hatch.
The Sarracenia produces pheromones and nectar trails, undetectable by us, which attract their prey and when they cannot resist and land on the plant it doses them with a chemical that makes them very happy, so that even if they don’t go into the mouth immediately, they are now hooked and will return to that exact plant (even if there are 10 just like it in the same area) until they drunkenly enter the pitcher’s mouth and slip into oblivion with a smile their face so that they don’t damage the plant.
The ones to call on to bite them mosquitoes back!
Sundews don’t just look pretty, but are also highly effective at catching mosquitoes and fruit flies.
These wolves in sheep’s clothing attract insects to their sweet, sticky dew-drops where they get stuck; after which the tentacles curl around the insect to maximise the surface area contact.
Nepenthes (Tropical Pitcher Plants or Monkey Cups)
These pitchers do not discriminate and attract a wide range of foraging, flying and crawling insects. They are however particularly effective roach and ant eaters!
The bigger they get, the more they can eat and in time these guys can each get big enough to fit a wine bottle inside!!
Don't be surprised to see geckos and mice peering in and stealing snacks from within the pitcher's mouth. They seem to have a symbiotic relationship, as they themselves sometimes find themselves on the menu, although not as often as you might think.
