I have an infestation of giant willow aphids. How do I get rid of them? What damage will they do?
Rate This FAQ
These type of aphids often appear in large numbers on twigs, branches, and trunks of willows. They can deform leaves and make a mess with sticky honeydew. They can also be a nuisance around homes by collecting on the sides of the house. One option is a strong spray of water to wash them off. Insecticidal soap products can sprayed on the aphids but avoid applying this product to windows. The plant can also be sprayed with horticultural oil. Another option is to treat the base of the willow or other ornamental plant with imidacloprid insecticide. This product moves through the plant and kills most plant feeding insects for up to a year. Do not use this product on edible plants.

- We found (we think) a black widow spider in our home last night. It is completely black with a red hour-glass shape on its belly. We are concerned that there may be more of them in our home.

I am particularly concerned about the safety of my children whose ages range from 9 months to 5 years. What can I do to get rid of any other black widow spiders that may be in our house, besides trying to keep corners clean, etc.?
