bringing houseplants inside for winter
What kind of insecticide do I need to spray my ferns and other plants before bringing them in for the winter. I am concerned about bugs as well as snakes. I have very large plants.

Spraying your plants down with a hose is a good way to get rid of bugs. If this isn't enough, neem oil is a good general insecticide that targets many types of insects.
I am not sure about the snakes, since there is no chemical you can spray to kill snakes. Sulfur is supposed to be a snake repellent, but I don't know how effective it is. Visually checking your plants is likely the best option.
