Can I prune my agapanthus plants as they're infested with mealy bugs

I have an infestation of mealy bugs in my agapanthus plants. I have used pest oil but that doesn't get rid of them entirely. Last summer many of the flowers grew crooked and were distorted with short stems. I thought it might help if I could cut the plants right down.

Dear Maggie,

Mealybug can be a difficult pest to eradicate particularly in strappy leaf plants as they tend to hide right down in the base of the plant where a contact pesticide like PestOil is difficult to reach. At this point in time I would suggest Yates Nature's Way Citrus & Ornamental Spray. This will control this sap sucking insect. You may need to spray more than once, spraying 2 weeks apart. You can cut the plants right down if you wish, but I would give the product a chance to work first before doing this. When you get the situation under control and have got rid of this pest, continue to monitor your plants just in case of re-infestation.
