A study titled “Tick killing in situ before removal to prevent allergic and anaphylactic reactions in humans: a cross-sectional study” has recently been published.  It is available open access from the Asia Pacific Allergy journal https://apallergy.org/DOIx.php?id=10.5415/apallergy.2019.9.e15   

Results from this published study support the use of ether containing sprays to kill ticks.  These sprays are approved by the TGA for use on human skin in Australia.  The study results also support the following ASCIA recommendations.

To prevent allergic reactions to ticks do NOT forcibly remove the tick. Disturbing the tick may cause the tick to inject more allergen-containing saliva. The options are to:

• Leave tick in place and seek medical assistance; OR
• Freeze tick (using a product that rapidly freezes and kills the tick) and allow to drop off.

The ASCIA document on tick allergy is available at www.allergy.org.au/patients/insect-allergy-bites-and-stings/tick-allergy    

Another recent publication reports on a second tick species that has been associated with mammalian meat allergy in Australia. https://synapse.koreamed.org/DOIx.php?id=10.5415/apallergy.2018.8.e31
