As the baits were consumed, the paper was replaced with soil and copious amounts of carton, leaving an outer shell; rolls therefore became heavier as attacks progressed.
Recalling a large number of the cartons of low-fat milk might increase the attack rate, but it might be decreased when two or more persons shared one carton.
This was due to the fragility of the milk carton traps; they were trampled by sheep and kangaroos, and could be eaten completely in less than four weeks.
All substrates are constructed with carton material.
They encased baits with coarse, external soil coverings and the large chambers and galleries excavated were lined with black faecal carton.
Bookbinders could use his discovery and carton-makers would be impressed by his paper's durability.
To assess the specific role of gardening ants, future studies need to compare carton nests from nongardening ants with true ant gardens.
The clear plastic covers were removed and the baits placed on top of the carton base, and the plastic sheets were replaced on top.
