Chemical: Ghost ant colonies are highly mobile and frequently move from overpopulated nests, making them difficult to eradicate. Contact insecticides can be used on colonies, but colonies may be composed of many nests, and killing workers is only a temporary solution. The best management technique is poison baits (Texas A&M University, 2008). Presto® (fipronil) and Xstinguish® (fipronil) have been highly effective at controlling certain ant species. These baits might also be attractive to T. melanocephalum because the target species have similar food preferences. Boric Acid is another alternative being investigated. The concentration of boric acid is too high in most available commercial baits but at low concentrations it has been shown to be extremely effective at killing laboratory colonies T. melanocephalum. Peanut butter and sweet solutions such as honey and sugar water are preferred attractrants of T. melanocephalum. There have been very few studies conducted which specifically consider control of T. melanocephalum (Texas A&M University, 2008).

1. AntWeb, 2006. Tapinoma melanocephalum
Résumé: AntWeb illustrates ant diversity by providing information and high quality color images of many of the approximately 10,000 known species of ants. AntWeb currently focusses on the species of the Nearctic and Malagasy biogeographic regions, and the ant genera of the world. Over time, the site is expected to grow to describe every species of ant known. AntWeb provides the following tools: Search tools, Regional Lists, In-depth information, Ant Image comparision tool PDF field guides maps on AntWeb and Google Earth and Ant genera of the world slide show.

Series of unpublished Landcare Research contract reports to Biosecurity New Zealand. BAH/35/2004-1.
Résumé: The invasive ant risk assessment project, prepared for Biosecurity New Zealand by Landcare Research, synthesises information on the ant species that occur in New Zealand (native and introduced species), and on invasive ants that pose a potential threat to New Zealand.
There is a great deal of information in this risk assessment on invasive ant species that is of global interest, including; biology, distribution, pest status, control technologies.
The assessment project has five sections.1) The Ants of New Zealand: information sheets on all native and introduced ants established in New Zealand
2) Preliminary invasive ant risk assessment: risk scorecard to quantify the threat to New Zealand of 75 ant species.
3) Information sheets on invasive ant threats: information sheets on all ant species scored as medium to high risk (n = 39).
4) Pest risk assessment: A detailed pest risk assessment for the eight species ranked as having the highest potential risk to New Zealand (Anoplolepis gracilipes, Lasius neglectus, Monomorium destructor, Paratrechina longicornis, Solenopsis geminata, Solenopsis richteri, Tapinoma melanocephalum, Wasmannia auropunctata)
5) Ranking of high risk species: ranking of the eight highest risk ant species in terms of the risks of entry, establishment, spread, and detrimental consequences.
NB. The red imported fire ant (Solenopsis invicta) is considered to be the worst ant pest in the world. However, Solenopsis invicta was specifically excluded from consideration in this risk assessment as this species has already been subject to detailed consideration by Biosecurity New Zealand
(This invasive ant pest risk assessment was funded by Biosecurity New Zealand and Foundation for Research, Science and Technology. Undertaken by Landcare Research in collaboration with Victoria University of Wellington and Otago Museum)

Résumé: PIAkey (Pacific Invasive Ant key) is an electronic guide designed to assist users identify invasive ant species commonly encountered in the Pacific Island region. The guide covers four subfamilies, 20 genera and 44 species.
The primary tool offered by PIAkey is an interactive key designed using Lucid3 software. In addition to being fully illustrated, the Lucid key allows users to enter at multiple character points, skip unknown characters, and find the most efficient path for identifying the available taxa. Each species is linked to its own web page. These species pages, or factsheets, are linked to an illustrated glossary of morphological terms, and include the following seven sections: 1) Overview of the species; 2) Diagnostic chart illustrating a unique combination of identification characters; 3) Comparison chart illustrating differences among species of similar appearance; 4) Video clip of the species behavior at food baits (where available); 5) Image gallery that includes original specimen images and live images (where available); 6) Nomenclature section detailing the taxonomic history of the species, and 7) Links and references section for additional literature and online resources.
