Thanks Lady Lee,
I work outdoors, I'm going to give the B-1 vitamins a go, starting now.
I've also heard that citronella extract is a good natural repellant, but I must admit that since I need good 30spf sunblock on during the summer the contact repellant that I've been using has reliable, nasty old DEET at 15% mixed with a 30spf block, just because the single application saves me time. If anyone is interested, it's made by "Croc-block".
The best information I've been able to come across indicates that of the almost 40 species of mosquito that live in my area, (SW Ontario) only 2 carry the West Nile Virus. Both species require dead calm stagnant, warm water to successfully hatch and through the larval stage of about 9 days.
We can help reduce the chances that these virus carriers will reproduce through some good yard and home maintenance:
* An old tire leaning up against a wall with a puddle of stagnant water in it is an example of the perfect breeding ground. Recycle them! If you can't part with your old tire swing, drill some drain holes in it.
* Check that your eavestroughs drain completely.
* Punch drain holes in the bottom of your garbage cans and recycling bins.
* Change the water in your birdbath regularly, ie: weekly.
* If you go on vacation, have your housesitter or a pool maintenance company drain your pool / hottub cover if it rains.
* I, like me, you have an old truck you only use as a "winter-beater", clean out any standing water from the box regularly. (If you want to put some drain holes into it, be sure you know where electrical, fuel, and brakes lines run!)
I'm sure you can think of other specific examples of spots in your yard you would check on. I'm not beyond noticing some obvious potential problems in my neighbourhood and politely knocking on their door to let them know. Most mosquitoes live and die in a 100 metre radius of where they were laid as eggs, barring transportation by humans.
By all means, take a stroll through the parking lot, yard and receiving area of you place of employment and report the potential breeding grounds you may see. Or, if you know your Health and Safety rep, ask them if they are aware of the need to eliminate the breeding areas for mosquitoes on their next workplace inspection, and ask for a follow-up.
Finally, if you see a place of business that has problems with storing old tires, drums, containers, vehicles, or covering things up with sagging tarps, ask to speak with the manager, or if you are a bit shy of confrontation, report the situation to your local Health Unit, and ask for a follow-up.
