Nine badger territories were estimated using bait-marking in Wicklow in 2009. The territories varied in size between 8.6 and 85.4 hectares (ha) and presented in a variety of shapes. Cubs were only detected in the bigger territories, suggesting a two-tier badger social system between those that breed and those that do not. It is proposed that non-breeding, small unstable setts be called peripheral setts. Bait-marking followed by counts can provide useful information on badgers.

Badger setts and territories were surveyed on the east of Great Island in Cork Harbour. They were bait-marked in 1995-1996, after bio-marked baits had been fed. Then, after twenty years, some setts were again bait-marked in 2016-2017. During the first period (1995-1996), there were 26 setts found on the island of which 18 were bait-marked, which revealed 17 territories. In the second period (2016-2017) there were 12 setts present in the same area that were regularly used by badgers. Of these, seven were bait-marked, but there were only two clearly defined territories. Bait-marking was useful in confirming the decline in badgers on the island.

Since the commercialization in 1995, termite baits have been introduced in 32 countries, protecting over 3.7 million homes and reducing pesticide use by more than 11,100 metric tons. Over the past 3 decades, advancements have been made to address the limitations of bait systems, including improvements in bait toxicants, bait matrices, and the frequency of required site visits.Termite baits have been applied in both commercial and experimental area-wide projects.This article discusses the factors contributing to the success of these projects and the key elements driving the progress and advancements in termite bait technology.

Bedbug infestations can be detected and eradicated even at the earliest stages with a new insect pheromone developed by scientists at Simon Frasier University. A thorough five-year study was conducted to identify the agent or substance that would lure and trap bedbug aggregates effectively. Biology professor Gerhard Gries and his wife, Regine, also an SFU biologist, with the help students and Robert Britton, a chemist at the same academe, the researchers were able to identify the chemical substance needed to bait the bugs.

The demand for bait by recreational fishers has led to significant commercial and recreational harvests of polychaete worms, primarily from wild resources. In this global review of over 200 papers, we identify 12 of the 81 families of polychaetes are used for bait (the most popular are Arenicolidae, Eunicidae, Nereididae and Onuphidae), and include over 60 species. There are clear regional patterns in the supply and demand for bait, reflected in harvest levels. For example, fisheries for polychaetes in many countries throughout Asia are focused on the supply and export of nereidids, yet in Japan, the nereidids are imported from China. Determining the sustainability and managing polychaete fisheries is extremely difficult due to: (1) a lack of a knowledge of the biology and population dynamics; (2) limited understanding of direct harvests as well as indirect impacts of harvesting; (3) reliance on wild harvest with few cultured species; and (4) problems with biosecurity associated with live exports. Improved understanding of the taxonomy, population connectivity, dynamics of polychaete populations and the fishery activities they support will support more effective and efficient management and secure more reliable access for user groups.
