Answer: While there are foggers you can purchase to rid your yard of mosquitoes, only the current population will be affected - the next day you'll have a whole new population and will have to spray again. An important step you can take is to rid your garden of breeding sites for mosquitoes. Water in birdbaths should be changed every 3 days; don't allow water to accumulate in saucers under your plants. Fill in depressions or holes in your yard so water won't collect and get rid of anything, from old tires to old buckets that might hold water after raining or watering your garden. I think your best defense is to slather on mosquito repellant prior to going outdoors. Off! is a good brand that contains DEET, which is very effective.
As for garden slugs, you can try trapping them or going out at night with a flashlight (that's when they do most of their feeding). Pick them up with a gloved hand and toss them into the trash. Or, use Iron Phosphate snail and slug bait (called Sluggo). It's very effective.
Best wishes with your garden!
