I pulled this fella out of my head last weekend whilst camping down the coast (I should say sheila as ticks with a 'beak' like this one are actually female and I believe are more potent), I must have been camped near a nest as I pulled at least 6 'out' of me over the weekend and had another 10 or so that I spotted bushwalking through my leg/arm hair

Didn't have any problems apart from some annoying itchiness which is persisting but I do know of people who have had hundreds over the years (They are fairly common where I live) with no serious ill-effects and then one day they got a tick and it had a serious effect. For example a close family friend & neighbour was found collapsed on the kitchen floor after suffering an adverse reaction and it was only the arrival of the ambo's with an adrenalin shot that saved his life, he was someone who had lived in the bush for ~30 years and had many ticks and never a problem. He now has an adrenaclick epipen in the car and another at home to treat any anaphylaxis if it happens again... and he's now moved to the city.
I've talked to a few people who believe we are having a bad year for ticks and there was even an article in the local paper this week from a local vet warning of the dangers of them to pets. A clear sign that your dog has a bad tick is when their back legs are starting to go wobbly but by this stage you really want to get them some professional treatment and trust me its a lot cheaper to find the ticks
before this happens, the vet bill is enough to make
your back legs wobble
I wonder what effect the warming climate will have on the proliferation of ticks and mosquitos etc around the world? they'll probably
ALL go to Tasmania (sorry, the title was about ticks in Tas I thought I'd better make my post relevant

)
ALWAYS be yourself.
Unless you can be outside, then ALWAYS be outside.
