Edit: this post has been moved to my new ant blog, Wild About Ants.
Just went out to check the aphids on the asparagus fern from last week. As I predicted, the aphids have virtually disappeared. I saw a few at the very tips of a couple of plant stems.
Insects have definite seasons and cycles, and it is worthwhile to pay attention to them. It can save you money, time and effort if you realize the pests are going to go away on their own.
Ants are particularly known for this. I think one reason there are so many wacky home remedies for ants is because people do something and when they check again, the ants are gone. The thing is, ants are highly mobile and it is likely they would have moved even if the homeowner had done nothing. (That isn't to say there aren't some useful home remedies, because there are.) When it comes to insects, being a procrastinator can really pay off.
