Before using any pesticide on a houseplant, carefully read the product’s label to make sure it is appropriate for both the pest and the plant.

When any houseplant is treated with a pesticide, be sure to keep the plant in a shady place, as pesticides and bright light often combine to cause injury to plant leaves. Use the following links as general guides; obscure houseplants are often not listed on pesticide labels. If you are unsure about a plant’s tolerance of any chemical, apply it to a test leaf and wait 3 days before treating the entire plant.

    2 of my bromeliads have what looks like sometype of larvae at the base of the plant right above the ground. Its a white substance, doesnt move, and will dissinegrate when rubbed between your fingers. Its definetely not insects but i’m thinking it could be some kind of larvae. ? I removed the substance 3 months ago and have sprayed it a couple of times but it just comes back. I have 100’s of bromeliads and these 2 Porteas are the only ones with the problem. They are healthy otherwise and both just put off 2 new pups each. Any ideas as to what it is and if so, is it harmful? If so, should i get rid of these 2 bromeliads to prevent my others from getting whatever it is?
