Springing Spring has Sprung in Northern California... I need tips on keeping the mosquitos away!

Our lovely garden, with decorative dog-repelling wire fence material to make it look ugly, but keep the idiot dog out.

 Well, here in the Northern end of the Great Central Valley, Spring is upon us.  You can tell it's Spring if you live on the edge of the Delta because the mustard begins to bloom.  We have a flower just about all through Winter -- sourgrass, or oxalis -- but when the wild mustard (which is everywhere here, along with bull mallow) blooms, we are at Spring.  Soon after, the wild radish will bloom alongside it.

Last year, in preparation for the big shed and house projects we were expecting, I moved a few plants that would have been destroyed.  I've done very little transplanting in my life, and I'm always scared, so I did some Googling and YouTube video-watching to get tips and tricks... but without the confidence that comes from experience, I'm always a nervous wreck.

The plants were a calla lily, a couple of roses, and a Japanese maple.  I know all three are hardy plants, and I shouldn't have been so concerned with the outcome.  Still, the roses have been wonderful -- they were on the property when we moved here, and are huge (one of them had grown well over ten feet tall) -- and the Japanese maple was a Mother's Day present the kids and I had bought my wife a few years ago. These have history, and I didn't want to lose them.

After transplanting, the calla never stopped looking alive, and the roses shot new growth almost immediately.  But the maple didn't do anything for weeks.

These leaves emerged almost immediately after transplanting back in November.  We've got a happy rose under our bedroom window.

Last week, however, the maple began showing tiny signs of life:

Success!  Tiny new growth emerging from the tips of the maple tree.

Since I was successful at transplanting four established plants, I'm now an expert here on the interwebs.  So here's my process:

1) Dig a big hole;
2) Pour some kind of plant transplanting help juice/water mix into the dirt left from the hole;
3) Dig out your plant, sweating and nervously chuckling at the horrible crunching and cracking sounds;
4) Put the plant into the first hole (not the second hole, that was made where you took it out, remember?);
5) Fill around the new plant with the dirt/transplanting help juice/water mix;
6) Pray and be nervous for 6-8 weeks.

I hope you gain something from my now publishable experience and expertise.

Something else that pops up in Spring is my archery class here in West Sacramento:

My backstop could use a dye job.

Sadly, we also get to deal with the perennial invasion of many, many mosquitoes.  My son gets especially large welts from some of them, but they are no fun for the rest of us, either.  What I need are tips for reducing/eliminating/fending off mosquitoes that don't involve bug spray directly on us, nor massive amounts of pesticide or pyrethrum or its chemical equivalent.  I know we'll never get rid of them, but the numbers are pretty amazing in my back yard.  (Yes, I know to remove standing water.)

Anyhoo, give me your tricks for getting rid of mosquitoes if you've got 'em.
