Mosquito-borne diseases are global problems. The use of topical insect repellents is a key measure recommended by health authorities to prevent mosquito-borne diseases. Despite more than a hundred commercial products available in the market, there are relatively few active ingredients used across these formulations. The most common active components are diethyltoluamide, picaridin, p-menthane-3,8-diol, ethyl butylacetylaminopropionate (IR3535) and a range of plant-derived products. Research has…

Three Molecules Found in Rosemary or Nutmeg Essential Oils Repel Ticks (Dermacentor variabilis) more Effectively than DEET in a Non-human Assay.
The results from examining individual terpenoids from two essential oils suggest that there remain unexploited natural compounds that could be further developed for new personal tick repellents.
Cellular and molecular mechanisms of DEET toxicity and disease-carrying insect vectors: a review.
To protect humans from malaria, yellow fever, dengue fever, zika, and filariasis, as well as to reduce economic losses associated with crop damage, considerably more efforts are needed to characterize the interactions between insects and insect repellents/pesticides to develop more potent pest control agents.

A review was undertaken of NSW Health's current recommendations on choosing and using insect repellents, taking into consideration recent research and currently registered topical repellent formulations.
Plant-based insect repellents: a review of their efficacy, development and testing
There is a need for further standardized studies in order to better evaluate repellent compounds and develop new products that offer high repellency as well as good consumer safety.
Field Evaluation of Picaridin Repellents Reveals Differences in Repellent Sensitivity between Southeast Asian Vectors of Malaria and Arboviruses
Scaling up of insecticide treated nets has contributed to a substantial malaria decline. However, some malaria vectors, and most arbovirus vectors, bite outdoors and in the early evening. Therefore,
Mosquito repellents for travellers
A pregnant woman visits you as her general practitioner because she and her children will be visiting a country with mosquito borne disease, as well as vaccinations and other relevant disease prevention measures, and asks which repellents would be best.
Tick repellents for human use: prevention of tick bites and tick-borne diseases.
In vitro and in vivo assays have been developed to identify molecules with repellent activities on ticks and more recently, plant-derived molecules, as an alternative to synthetic molecules.

The available evidence on the effectiveness and safety of DEET-based products is reviewed and it is found that the evidence does not support increased risk in young children.
Assessment of methods used to determine the safety of the topical insect repellent N,N-diethyl-m-toluamide (DEET)
This review compares the toxicity assessment using three different models to define the risk assessment and safety threshold for DEET use in humans and discusses the clinical consequences of the thresholds derived from the models.
