Ants in my dishwasher
« on: July 31, 2009, 08:01:40 AM »
Got a wierd one.  I have large black ants in my dishwasher.  I had them earlier this summer and finally got rid of them simply by getting rid of as many as possible.  However they are back again, and only in the dishwasher.

I don;t unerstand how the hot water does not kill them off or how they are getting there?  My wife says that since we had them in there the first time the dishwasher does not seem to be cleaning as well either.

Does anyone know of anything I can run through the dishwasher to kell them off?  Any idea where they could be living that is not affected by the water?

Ants learn to enter the tub by several methods...the water inlet on the left side has a wide air gap they can march into from the outside. The blower vent also has a large opening and so does the door flange around the lower door area.

Your best bet is to remove the lower panel and place a pan of Amdro or other ant repellent under there to intercept their journey.


Regarding the cleaning issue, be sure the water valve is letting enough water in to power the pump. Had you provided a brand and model of the unit in question, perhaps more solutions can be presented.

I s'pose you have carpenter ants in Canada--which are the "big, black ants" we have in the mid-Atlantic US.

They colonize wet, rotting wood, so they are commonly seen in areas where overflowing gutters, inadequate caulking and other water-leaking situations affect the surrounding wood.

I like to think of carpenter ants as an "early warning" system for carpentry, plumbing and like problems, rather than as a pest control problem. Get rid of the damaged wood and the source of the water that caused it, and the ants will go away. Baiting with poisons or worse, spraying, just treats the symptom (ants) rather than the root cause rotting wood).

Maryland Extension has a good fact sheet with more info:

As far a rotting wood the kitchen is new, and I know I have nothing rotting, as I have been able to check for that exact thing all around the area.

OK so that's a basic Whirlpool -made unit. Your tub should fill to just beneath the heater element for the thing to wash properly. If it does not, you just need a cheap water inlet valve. Also, a good dose of white vinegar once every couple of months will do wonders for dissolving calcite and scale that may get down in the filter screens and impeller area. Let the unit begin to fill, then add 1 quart of white vinegar directly to the tub (no soap) and do the short wash cycle.
