They are the enemy of many who try to grow plants indoors with living soil
The bugs go after the sap, and especially like new growth, but you may see them traveling up from the soil, or going back to lay more eggs
You can either try to start them in sterile soil or try to fight the bugs
There are probably some good discussions about this -- if I recall
Thai peppers from the store -- plant the seeds, or buy a pack past its prime and plant the soft ones whole...
I love Thai peppers -- they will grow in a
bucket with holes in the sides along the bottom and can harvest 2 bursting ziplock baggies full out of one seed and one bucket!
And they're medium heat which is
enough for me!
