I have treated several Ficus trees with Merit for Rugose Spiraling Whitefly and have had great success. However, two of the trees seem to be in shock for the past 6 months. While most produced new leaves last spring some remained bare with no growth. Under the bark they seem to be alive with green, moist tissue, but no leaves.

I got a call from a client who is having pine tree problems. The pines have a little worm eating the inside 'tips' of the pines.

I've been treating a 12 ft ficus around a condo association with Dominion and Orthene and treated them 3 times more, once a month, with permethrin. Yet they still seem to be coming

Two customers have called me today about hundreds of caterpillars crawling on their patios and driveways, coming into their garages.

Fig whitefly - where did it come from and what is the cheapest way to control it? Is there any home remedy such as liquid soap, garlic, or something natural, even if I spray monthly. I know about systemics, but they are very expensive.

I had a customer ask me how to get rid of lichens on her trees? I haven't found anything labeled for lichens. I read one note that said they are sensitive to sulphur dioxide, a primary constituent of acid rain.

I was given some leaves with a "pea pod" type larva attached to them. The pods are green and go thru the leaf onto the other side. What insect is this.
