Mystery tiny bugs destroy impatiens. Help

mehawkesJuly 14, 2011

I have successfully grown impatiens indoors for some years. They are not the New Guinea ones but the normal single flower variety.

The last three plants have been killed by a bug that I can't identify or kill.

It is long and thin but tiny - length is under 1mm. It is between white and green in colour. It doesn't fly. It hasn't infected any other houseplants.

The bugs gather round the edge of the leaves and eat them moving towards the center of the leaf. This leaves the plants a shrivelled mess.

I have tried greenfly (aphid)killer, sulphur solution and washing up liquid solution all to no effect.

I would be hugely grateful if you could tell me what these bugs are and how to kill them.

I'm thinking that these might be little thrips. Do a quick check around on the internet to see if it's a match for you.

Thanks very much for your help; I think you're right. I strong salt solution seems to have killed them.

Killed the thrips AND the impatiens? ;-)

I love impatiens but I am also sick of them getting all kinds of bugs and diseases. toward the end of the summer, they always start dying or majorly going down hill from one problem or another. I will always have some, but I am going to more geraniums now, because they are basically care-free and, like impatiens, come in so many colors.
Good luck with yours!
