Those Darn Ants!

For 2 weeks, I have had very small ants wandering around the TV room and adjacent kitchen.  They show up just inside the deck door, the kitchen windowsill, and on the backsplash board on the counters.

OK, ants seek food and sometimes they find their way into the house, but they aren't acting normal!  There is no trail of ants going anywhere.  There is no sign of them outside the house.  There is no paricular entry point I can detect.  There are never more than a few at a time, but there are ALWAYS a few any time I look.

They aren't in the pantry at some loose food box (I moved everything around and looked with a flashlight), they aren't at the cat food bowls, they aren't in the cabinets (flashlight again), they aren't even at the compost bin which is the main thing I would think would attract ants. 

They aren't in the ceiling of the basement below the kitchen or the TV room. 

Hey, this is vaguely sounding like a Dr Seuss poem...  I'll have to work on that idea!

I sprayed only once right under the base of the deck door inside and out (and then cleaned the exposed floor because the cats found the smell interesting).  I'm not too worried about the effect of the (organic) ant spray on cats because the stuff won't even annoy wasps and wasps evolved FROM ants (or vice versa) so they are very closely related, but why take chances.  But the limited spraying had no effect on the few ants visible at all times.

The point is that I can't figure out WHERE they are coming from, WHY they are in here, WHAT is keeping them searching around, or WHEN they are most commonly seen.  It seems completely constant, yet completely random.

I've probably killed over a thousand by finger and shoe.  It doesn't seem to make any difference if I kill them or not.  When I crush all the visible ones, there about as many in 10 minutes.  Yet after not bothering them all night, there are still ONLY as many in the morning.

ON THE OTHER HAND, I haven't yet had a fruit fly (aka fungal gnats) yet this year, and I usually have problems with them by now.  I'm pretty sure the ants aren't catching the fruit flies, but bigger theories have been proposed on such coincidental observations, LOL!

I expect the ants will simply stop appearing in a few days and I will never know why they where here or why they left.  It will be one of those mysteries of nature; those "Ants In My Midst".
