Tracking Insecticide Use, Presented by Dr. Bill Robinson, B&G Equipment

We had another great presentation from Dr. Bill Robinson, B&G Equipment at the 2012 New York Pest Expo. This year he shared with us his expertise in the use, and often, misuse of insecticides.

According to Dr. Robinson, monitoring the use of insecticides is one of the most important parts of professional pest control today. Tracking product use and monitoring its application can help to save an operation a lot of money and effort.

When spraying insecticides, what a tech basically does is apply droplets. Once they dry the light residue left behind is what will kill the insect. There is no need to over-apply. This is wasteful. You can only kill the insect once. More product will not kill it more.

The same can be said about dust applications. A paper-thin layer is all that’s required. If you can see the dust, you’ve applied too much.

What is over-application? Spray to run-off, dusting to a thick coating and re-tracing over a previously treated surface.

Over application becomes a bad habit that is hard to break. We often feel the “need to squeeze”, as Bill would say. This need will cost you money. If a tech services 15 accounts a day and sprays an extra 30 seconds at each stop,  that will equal an over-application of 1 gallon in a single day, or 20 gallons in a month and 240 gallons for the year! What a loss. Kill the bug, don’t kill your profits.

Avoid using cone-spray nozzles in urban pest management. They are primarily designed for insecticide applications to plants.  They put out 2.5 times more output than fan-spray nozzles and 14% of the droplets don’t even hit the target.

Old, worn out or damaged equipment will also result in misapplications. Old nozzles waste insecticide and money. Worn nozzles can increase flow rates up to 17%. Remember to replace your nozzles after 350 gallons of use.

When it comes to insecticide use, just remember: the things that count are the things you can count.
