flypaper

It's made of sugars -- acylsugars, to be precise -- and acts as a sort of natural flypaper for would-be pests.

Still today, the pit attracts and inadvertently immobilizes mammals, birds and insects like “flies on flypaper,” according to Bird Center’s statement on the incident.

The bubbling tar, or asphalt, has previously captured small mammals, birds and insects like “flies on flypaper,” according to the International Bird Rescue.

Det Con Stephen Williams from Dyfed Powys Police described a cluttered room, with flypaper full of flies next to a 16th birthday balloon and cards.

A strip of flypaper dangled from the ceiling.
