Should you discontinue service if you don’t see bugs?
The one thing I can assure you, is that bugs can hide extremely well. They can hide in the smallest of cracks, under rocks, or just about any nook or cranny. Just because you don’t see them, they are there. The more harborage areas, that’s where they hang out during the heat of the day or the cold of night equals the possibility of hiding bugs.
So lets say you have crickets, well scorpions just love crickets so by continuing to eradicate the crickets means that the scorpions won’t have any food. The less food = less other predators. Less hiding areas = less predators.
So by continuing with a pest management plan = less bugs in general and the probability that you will continue to have less predators in place as well. The other issue in the southwest is the lack of real cold, enough to freeze or kill the bugs. This year as in the past year we haven’t had a real cold to kill off the bugs and that is going to mean bugs… and lots of them.
So I would keep the pest control going, less bugs = less bugs in your homes.
