Thanks, rhizo_1.

I really hope it isn't leaf miner. From what little I read online, it seems to be harder to get rid of than aphids (and more insidious). I tried holding the leaves up to light, but they were too withered to get a good view. I have a peppermint plant near the mint that doesn't seem to be affected yet. I guess I will be moving the peppermint to another window.

Any suggestions for getting rid of the leaf miner on an indoors plant besides neem oil or wasps (which isn't an option)? Would regularly plucking off the affected leaves help? Also, is it possible the leaf miner originated in my home or was it there in the plant when I purchased it?

Unfortunately, by the time I got my mint home it was suffering from shock - it took me a while to get home and the mint was not happy in the plastic bag I had it in. It took about 2 weeks before the mint was back to normal and before I realized the affected leaves were not the result of the shock but a pest.

Okay, so I took another and much closer look at my mint and found several whiteflies. Is it possible this is the work of the whitefly and not leaf miner? I tried looking for examples of whitefly damage to plants but couldn't find any good pictures, just a lot of pix of plants covered in whiteflies.

If my issue is with whiteflies, does the yellow sticky traps really work? I read that using aluminum foil under the plant helps repel the whiteflies.

I can only go on the photos, but whiteflies usually leave traces of white mould where they've eaten. The white flies could be thrips. The black stuff could be frass from leaf miners or it could be faeces from thrips.

I don't think traps are going to make much of a difference. The plant is so small, I would either go through each leaf individually and remove what you can see or spray it with a strong jet of water.

If you can possibly put the plant outside do so. If not put it ion thelightest place you have and give it as much fresh air as possible. It won't cure the problem but will make it less likely. Your mint will healthier and more resistant to challenges. At present it is beginning to show signs of etiolation due to lack of light and the resultant soft sappy growth makes it easy prey.

Sophie - Urgh... hopefully, it's not thrips. I definitely do have whiteflies
which I verified late last night. Okay so as of now I have whiteflies and
possibly leaf miners (or thrips). Just need the aphids to make an appearance.

floral_uk - The window is the only option. The mint is facing south and I keep the window open for most of the day so it gets quite a bit of air circulation. The mint looked like that when I purchased it and it actually has improved quite a bit since the initial shock. There is growth near the soil and in recent days has more leaves, though it's hard to see in the picture. I wish this was a lack of light issue than an insect issue. I spent the morning pulling off more leaves... not good.

Not thrips damage. That looks quite different.

Phew. Good to know it's not thrips, because the only insect I saw (besides the flying carpenter ants) looked like thrips.
