[url=https://www.theguardian.com/global-development/2026/jul/07/catnip-lotion-as-effective-as-deet-at-repelling-mosquitoes-study-finds] maybe no blackfly problem but you might develop cat rash [/url
other plant based ones include bog myrtle, garlic and citron oils
deet/dmp are ace but hard to forage or grow
bog myrtle and garlic and citron and lavender(and paraffin and mud) i knew about but catnip is a new one in the repellent herbal
if i had midgies or cleggs i could do a trial, i dont and i aint going looking for them
mossies should be on the test list, the most dangeroos critters on the planet still need mitigations
Unfortunately ours don't. They are worse near the fields, but we are still getting some in the middle of the wood. I was definitely got by one and another couple tried to get me. Not sure if they did, as I haven't swelled up, but rather itchy in the area. They are all now ex-flies.
