I don't choose the ads. I use Google's advertising platform and they select the ads. If I can track down that ad -- which I haven't seen myself -- I can block it specifically. But, given the huge number of ads that run here, it is often hard to find an individual ad to block.

I keep winding up with an ad for The Hitmen (exterminators?) on this site, and they show ants crawling around. I have a huge phobia and it freaks me out every time. Can you let someone else advertise on your site? Someone whose ad doesn't include crawly things?
