I think it's just because so many of them take to the air at the same time. You might think a lot are trying to get in but they're just a small fraction of what's outside!
I've had the unfortunate experience of mountain-biking on flying ant day. I got plenty of protein in my diet just breathing while going at 20mph or so

@Indy, the ichneumon wasp (there are a few varieties here in the UK) is a parasitic insect. It's got a remarkably skinny long abdomen and several species have a couple of stripes, probably to fool predators into assuming it's a wasp. The females will lay their eggs in another insects larvae (such as a beetle grub) and the young will hatch inside the larger insect and then devour it from the inside out. Alternatively they lay their eggs near a grub stuck in rotten wood or a fruit, once the eggs hatch, they have a captive source of food that will continue to get bigger as long as they're selective about how they eat it!
Here's an example of a female of one species; complete with ridiculously long ovipositor: Click here

every day's a schoolday! thx Rec i didn't know that, I get a bit paranoid about our infestations because livi9ng on the edge of a big marsh it's like the Plagues of Egypt at times.

You said they crawl out of your floor boards Mr. Mullah. I took that to mean underneath and within ... which led me to suspect a nice ideal setup somewhere beneath your floor for "en ennnt kolonny."

And I guess Rec is saying that when the new queens mature to star their own, it is like "Grand Central Station" and devil take the hindmost. They all just dash out any which way they can.

@taw hey forget the sprays get ff he just "shoots" bugs
