At the beginning of fly season you should start with a clean drum. If you didn't clean the drum when you winterized the system, you will want to use a bleach solution to clean out any slimy build up. (This should be done at least once per year.) The insecticide is biodegradable, so it will rot over time depending on your water quality.
*TIP* If you have some insecticide left in your drum pour it on ant hills, put it in a sprayer to use around foundations, feed rooms, tack rooms or other areas where you might find bugs.
*TIP* Adding a cup of bleach or AgriSyn when you fill the drum will help kill any bacteria and prevent the insecticide from rotting.
*TIP* Rinse your insecticide bottles to get out all the insecticide. DO NOT overfill the drum - leave about 10" at the top of the drum
*TIP* Your system is designed to shut off when the fluid level is low. Each time you refill your system be sure to rinse the filter in the drum to remove all debris and any build up.
