Geranium (Pelargonium graveolens) Back in the late 80’s and early 90’s, Geranium oil was so successful as a big carp catcher, anyone and everyone making bait at home used this at some point! An all-time classic bait additive. Aromatic description – floral, fresh, sweet, with a fruity note. Geranium oil as a bait additive can be second-to-none in spicy base mixes. We found 2 drops to work well on it’s own, but even better when blended with 3ml of CarpBaitUK’s under the counter caramel powder and 1 drop Caraway – then just sit back and wait for the scream from the alarms!.
