I moved the Philodendron Xanadu to the front porch of my house which is enclosed and it is doing much better and I will move it indoors completely soon. It gets tiny aphids mainly on the back of the leaves. I have sprayed it with a house plant pest spray containing fatty acids its (been in the garage a long time perhaps it's gone off.")as they seem to keep coming back. Can you reccommend a treatment please?

I have a Parrot Plant (indoor) it is infested with white fly .I have sprayed continually and even washed each leaf and stem with the spray but no avail . Its still infected and even the floor around it gets sticky .what causes white fly and how can I get rid of it.

A small beetle is killing of a house plant, can you suggest a treatment after re-potting with new fresh compost.

I've got vine weevil in my indoor pot plants. I've seen some adults & got rid of them. What can I use to control them? I've got a lot of indoor plants & don't want to throw them out especially a Ficus that I've had for 10 years. Would it be best to repot everything & use the nematodes in case any larve remain or to use a chemical control.

i keep finding this white stuff on dead plants in my indoor garden. Is that what is killing my plants? Please see photo attached
