Cedar Oil

Does anyone here know if cedar oil has any positive or negative effects? I am looking to have a sprinkler system installed and the installer can also install an attachment that can spray cedar oil in the yard that is supposed to repel mosquitoes. Do you know if it actually works to repel mosquitoes and kill mosquito larvae and eggs? The sprinkler system will not touch my SFGs because those are watered by my own drip system. Some grass, leaves and other material from my yard will be exposed to the cedar oil and end up in my compost barrel. Can this cedar oil make composting take longer than it should? Any other views on the cedar oil?

It's funny how once you start gardening and composting you find that everything is (or should be) connected. If I didn't have a garden I wouldn't really care what was sprayed onto my lawn if it actually kept mosquitoes away.

Mosquitoes breed in pools of standing water. If you don't have standing water, there is no mosquitoes breeding in your yard.

This is an interesting read about the buggers, with some good advice about them, the life cycle, tolerance levels and management of them.

Ditto camprn and add flowers to attract hummingbirds.
Attracting Hummingbirds to Your Yard
"An adult female can consume up to 2,000 insects per day. Small invertebrates including mosquitoes"

I guess I should have been a little more clear. I know mosquitoes lay eggs in water but the guy claimed it would kill the eggs and larvae which I don't care about because I don't have any standing water. I was more interested in it being a repellent. I'm guessing if it does have a repellent effect that it wears off within a short time.

My bigger question was what effect it might have on things going into my compost pile. If cedar is good material for boxes because it is rot resistant then will it slow down my compost pile?

I like the idea of attracting hummingbirds or bats to my yard to eat their fill of mosquitoes. Here the mosquitoes are almost humming bird size. I would love to see these oversize mosquitoes battling with hummingbirds.

Here's a link to cedar (not oil itself but chips etc) that may help answer your question

LOL big mosquitoes

I don't know about cedar oil, but there is a product called "Mosquito Barrier" that is almost pure garlic juice. It works wonderfully! It also works on ticks. And it supposedly works on a lot of other things, like fire ants. We used some last summer in NC because there is a huge tick problem there (waaaay out in the country) and also mosquitoes. I've ordered some to use here in Savannah this year, but I haven't put it out yet. You just add it to water and use a sprayer (like you would use to apply pesticides). You can also use it on bodies of water (like a pond). You have to add some oil or detergent or something (can't exactly remember) so it doesn't dissipate in the water. You do have to reapply it periodically to keep it working, but it's a great way to fight some nasty bugs naturally! We have a huge fire ant problem here, so it'll be interesting to see how well it works on them. NOTHING seems to get rid of them!

OH, and we were outside one evening before I had applied it to the yard, and the mosquitoes were eating me alive! (they LOVE me for some reason!) I just opened the bottle and set it on the ground nearby, and they disappeared almost instantly! I have to warn you, the garlic smell when you open the bottle is overpowering, but once you put it on the yard it goes away pretty quick. It still keeps them away though, for several weeks.
