What does this?

This is directly in front of our front door -Note the two piles of dust around the joint in the slabs. Yes, we have a dog whom we usually let out via the front, in via the back door (don't ask). Usually on her way out she examines the that area, but today I spotted the piles of dust around the joints in the slabs. It is not something she would usually do.

Eggtimer Ants. Apparently it only takes them 3 minutes.

Giraffes, according to EFLImpudence.

No, I don't give up. Please explain again how ants is the only word that can be used to describe these insects:

This is a giraffe:

Thanks all, we have had lots of problems with them in the kitchen, which is at the rear. I had better do something about them, before the take up residence at the front.

I find the Nippon gel (liquid) best. It is so delicious that they take it back to the nest to share with their friends.

Put a few drops on non-absorbent surfaces such as clean coins where the workers will find it.

Unlike powders and sprays, it is not a contact poison, but a sugary food.

replace it after rain, or when it is gone or covered in dust and grit.

I find it takes less than a week.

A £3.50 tube will last you years.
