My basil plant had one neon green worm like caterpillar bug (exact color as the basil leaf so he blended right in). Many of my basil plant leaves were eaten up and there were about 40 or 50 black hard bead like poops from the caterpillar all around my kitchen counter under the basil plant. I found this lime green caterpillar having a feast on the underside of a leaf! I put it in a zip lock baggie and he produced a poop in the baggie!!! (no I did not collect the poop from the kitchen counter.) He is going in the trash with all the poop!!!!! See photo of bug!

Noelene, I'm guessing the problem with your ficus is aphids. Do they look something like the ones shown ? If so, just set the plant in your bathtub, then mix a bit of ordinary dish-soap w/ water in a spray bottle and spray them off. You can also spray them off with just a stream of plain water. Ficus are sensitive, so make sure the water you use is tepid (slightly warmer than room temp). RInse w/ clear water when you're done. Check the plants each day and repeat the process if you see any aphids return. Alternatively, you can just squish the aphids with your fingers, but that's sort of yukky. lol! If it's not aphids, can you post a photo?

That's it - thanks Mick, I appreciate the help. :-) Guess they're not such a good bug afterall.

Thank you all for your answers and sorry for taking so much time in coming back with more info! I took a few pictures which i hope will be more useful than the previous one. I fear this plant cumulates the issues. As you can guess from the pictures, this is an office plant and it probably doesn't get the needed TLC. I suppose it needs repotting. In fact it's not mine but I took care of it during it's owner's prolonged absence. It is next to a window and gets a bit of the soft office ventilation. I water it generously once a week. It has time to dry for the next watering. I don't put fertiliser, just plain water from the tap that I put in an open bottle the week before. I just pruned those ones: The leaves at the top and the bottom are the most beautiful ones. The ones in the middle are weak. Hopefully, you can see the larvae and flies: Can you hereby ID it? Another issue? Thanks again for your time!
