I was born and raised in Alberta, where the summers are hot and dry and the winters are cold and dry. I don’t mean dry as in no precipitation but dry as in the air can make your skin flake like a 10,000 year old mummy’s. And the water is mineralized enough to leave scales on taps and pipes the envy of any dragon.
Calgary gets rain (thundershowers), hail (in buckets) and snow that lasts a winter. Or at lease these phenomena were common in my childhood. Because of this you never saw an animal with fleas unless it was in a place particularly dirty or the animal was particularly mangy. And head lice was not something we even had to worry about in school. However head lice and body lice have been around since humans started wearing clothing (if not longer).
Now I don’t know if head lice care about cold or not, or if people washed more frequently or just didn’t get near to each other but we certainly never had warnings or even one kid with them when I was in school. However, infestations have been reported in most countries and a huge increase has occurred in the last 20 years. I don’t know if this is climate change or that these little vermin are just finding humans more appetizing.
I didn’t encounter head lice when I moved to Vancouver, but I did encounter fleas because of the warmer and moister climate. Your cat or dog doesn’t have be mangy to get them. Keeping a place clean certainly helps. I did encounter lice in the US though.
I used to go down and visit friends who had two kids. I’d sleep on an air mattress on their living room floor and play with the kids as well. I never even knew about lice really at that point. But one day a few weeks later I was at my desk and reading a paper, and scratching at my neck. Now due to my sensitivity to some foods, getting a rash around my neck was not unusual. What was unusual was that as I scratched a little born ovoid bug fell onto the page. At that point I frantically rubbed my hand through my shoulder-length hair and watched in horror as more bugs fell onto the page.
My skin crawled and I panicked. I ran to the bathroom and brushed and brushed and combed my hair knocking beige vermin into the sink. I looked over my scalp but really couldn’t seem much there but I knew. I think with a bit of internet searching and calling a few friends I figured out pretty quickly what I had and went to the pharmacy for louse shampoo, which came with a lovely nit comb. Nits are the egg casings of a louse and stick to the air as little white dots. They’re small but tenacious, and so are their parents, the lice.
The full process involved shampooing my hair and, because I didn’t want to shave my head, sitting outside (thankfully it was summer) on my patio and having a friend comb every nit from my hair. Two-three hours later, I was nit free but still had to shampoo a few more times over the week and check to make sure the buggers were gone.
Besides the bodily care there was the washing of all clothes and bed clothes I may have come in contact with during that time. As well, I had to bag pillows or items that couldn’t be washed and dried under a high heat. I had to vacuum everything thoroughly and leave those bagged items for up to a month to make sure everything was dead.
The worst part was that all of this could have been prevented if the friends, who knew their children had lice, had just let me know. Instead of being head in the sand like they had been, I took the onus of contacting everyone I’d been near to tell them about the lice and what to look for. It was like contacting people to say I had an STD. I felt ashamed and mortified yet I was responsible.
I never stayed with those people ever again but had the misfortune a few months later of being at a group camping event where they were at. I went home and found a few lice but caught them right away, and again informed everyone I knew. I think part of the reason these vermin infestations have been spreading is that people don’t take responsibility. School age kids are most susceptible because of their close contact and therefore schools have a huge problem. We’ll never eradicate them as long as there are people but we could get them under control with a bit of knowledge and responsibility. And I hope I never have to deal with any parasite on my body again, besides slapping a few mosquitoes.
