Repellents are biocides and a proof of efficacy is required for active substance inclusion as well as for product authorization. Here, we describe two test systems for efficacy evaluation of ant repellents with the substances DEET 50 %, Margosa extracts 100 %, baking powder: sodium hydrogen carbonat...

In the European Union, baits against pharaoh ants (Monomorium pharaonis) have to be authorized as biocidal products. The dossier to be submitted for authorization of the product has to include a proof of product efficacy. No consistent test standards have been established by the European Commission....

Baits (station, granule, gel and liquid) are widely used in the control of ant pests because of their effectiveness, ease of application, and their reduced risk to people, pets and the environment. Among the types of baits, gel baits are the most popular bait type for ant control. However, after app...

A novel semi-liquid ant bait matrix containing imidacloprid between 0.001 and 0.1% destroyed all laboratory colonies of Pharaoh’s ant in a dose related time span. Best performance was observed with concentrations ranging from 0.01 to 0.1% imidacloprid. Two concentrations (0.01 and 0.05%) were field ...

The Urban Pest Advisory Service (UPAS) is responsible for urban pests in the city of Zurich, Switzerland. We give approximately 2,000 consultations per year concerning pests and their control; we survey the pest situation in the city and control rats in public areas. Through a survey made among pest...

Choice experiments determined sucrose bait base preference by using laboratory colonies of 10 species of urban pest ants, namely Monomorium pharaonis (L.), Monomorium floricola (Jerdon), Monomorium destructor (Jerdon), Monomorium orientale Mayr, Tapinoma indicum (Forel), Tapinoma melanocephalum (Fab...

Climatic changes, tourism and travel, intensive product deliveries, especially of tropical plants, all contribute to the growth of ant infestations in Europe. These rapidly adopting ant species might need to be more thoroughly learnt and understood and possibly new, inventive eradication systems be ...

Tapinoma melanocephalum F. (Ghost Ant) infestations have increased in Western Europe. Generally, Ghost Ant infestations resemble those of Monomorium pharaonis (Pharaoh’s Ant) with a focus to older, multi-unit apartment blocks which offer a multitude of nesting opportunities and easy migration of ant...

The Pharaoh’s ant, Monomorium pharaonis (L.) is an important species in the urban environment. This paper discussed the performance of a new bait formulation containing S-methoprene. Discussions are made on various laboratory experiments (in Budapest, Hungary and Penang, Malaysia) and field trials i...

The feeding responses of three urban pest ant species, Monomorium pharaonis (L.), Monomorium floricola (Jerdon) and Monomorium destructor (Jerdon) after being subjected to nutritional starvation and satiation (either for all nutrients, carbohydrate only, protein only or lipid only) were studied usin...

The Pharaoh’s ant is one of the utmost cosmopolitan pest species in the world. Its notoriety in bacterial transmission at hospitals through sterilized apparatus makes it an even more burdensome pest. Over the years, many studies on the control of this species had been conducted. This includes the us...

The Pharaoh ant, Monomorium pharaonis (L.) is an important pest ant species in many parts of the world. Knowledge and understanding of feeding behavior of this species are essential to the success of baiting. Transfer of a toxicant in a bait to kill a targeted colony depends on the ability of the nu...

The impact of noviflumuron on whole colonies of Pharaoh’s ants,Monomorium pharaonis L., was investigated in a series of laboratory experiments. Large colonies (tens to several hundred queens, 0.5 to 2 grams brood, and 2,000+ workers contained in nine cm diameter by two cm high plastic Petri dishes w...

Questionnaire-based surveys of homeowners revealed that ants were the most economically important and abundant household pest after mosquitoes and cockroaches in Malaysia. Twenty-five species of ants were found indoors and outside buildings; all species nest outdoors except Monomorium pharaonis, Mon...

Pharaoh ants, Monomorium pharaonis, are significant pests associated with man and his environment. Chemical sprays are not ideal control methods if they cause the ants to disperse. There is a preference for bait treatments that provide a means to use ant biology to transfer slow-acting compounds int...

Efficient control and eradication of Pharaoh’s ant is a difficult task for PCOs mostly due to the fact that several queens live in a nest, all of which can not be killed with traditional methods. PROTECT B Pharaoh’s ant killer bait is a special ready-to-use formulation that contains an insect growth...

The Pharaoh’s ant Monomorium pharaonis (L.) (Hymenoptera: Formicidae) is a widespread urban pest, being most common in large, heated buildings. Fipronil is a novel phenyl-pyrazole insecticide, effective against insects of urban importance including termites and cockroaches, being active by both oral...

Pharaoh’s ants, Monomorium pharaonis, are one of the more difficult indoor pest ants to control. We studied if routine exterior monitoring and initiating baiting when infestations are incipient, will prevent infestations inside a building. The study was conducted at a 7,841 m2 two-level building wit...

Controlling Tapinoma melanocephalum (F.) can be extremely difficult and lengthy since the ants’ appearance inside a building may vary by day and the location. There are no long lasting ant trails like in other species and even the preference for food may vary within the day (carbohydrates, fruit jui...

Records of visits to 22,615 dwellings in the London Borough of Southwark, for period October 1993 to December 1998, were examined. Data were analysed for ghost ants (Tapinoma melanocephalum Fab.), pharaoh ants (Monomorium pharaonis L.), house mice (Mus musculus L.) and brown rats (Rattus norvegicus ...

Containerised insecticide bait products offer considerable advantages for control of urban crawling insect pests. However the differences in insecticide susceptibility and food preference between some pest species have resulted in a diversity of commercial bait products, each targeted at specific in...
