Shovel the litter into a garbage bag for appropriate disposal. If you must transfer a pesticide to another container for disposal, clearly label this container as to its contents. Never transfer pesticides to non-pesticide containers except for immediate disposal . Someone may accidentally drink the contents assuming that it is a beverage. Liquid pesticides in undamaged plastic bottles should be salvageable.
Most pesticides are water insoluble and turn milky-white when water is added.
Any pesticide that you suspect is contaminated should be discarded, rather than stored. If the pesticide container label is damaged or lost, get another copy of the label or else write the name of the chemical on the container, then discard it. If you can't dispose of damage pesticide containers immediately, place them in a secure area where children, pets or wild animals cannot reach them. Thoroughly rinse rubber gloves and boots worn while handling damaged pesticide containers. Shower or rinse contaminated areas of skin thoroughly .
