This sounds obvious, but you know what they say about common sense (it is not that common).
I did a quick video to share some thoughts on some of the health and cost factors that come into play when you don't keep your spray equipment in good, clean condition.
Some of the photos in this video may be surprising, but I promise you they are real.
The one photo shows the power spray rig nightmare scenario. The worst case situation of not keeping your pest control equipment clean.
Please take a look and let me know your thoughts.
