Recipe for Plant Sprays/Insect Repellents
Comments (7)Thank you all for your advice (sorry for the late thank-you -- have been having intermittent computer problems). I wish the prevention part were that easy -- we live in Va. Beach and our property is on the Lynnhaven River -- fairly brackish shallow muddy and probably mosquito nirvana. Our property has a "dog leg" strip that goes down to the water, but we haven't cleared it yet (and legally I'm not sure how we'll wind up doing that -- harsh restrictions because they're trying to revive historical oyster beds). That area is full of marsh grasses, poison ivy and lots of muddy puddle areas. The perimeter of the rest of our rectangular lot is fairly heavily covered in trees, azaleas, ivy, etc. -- lots of hiding places. We're working to clear it somewhat (replacing ivy with mulch) but I also am torn -- I like providing habitat for wildlife (and we have plenty!). I think the biggest problem are the Asian tiger mosquitoes. They're out all day and are so small and fast -- and from what I've read can breed in 1/4" of water very quickly. We purchased one of those pheromone/CO2 traps (is supposed to lure them in where they're fanned into a tray of soapy water) and caught lots of moths. I called the manufacturer in New Zealand and was told that "oh -- they'll work on pretty much all mosquitoes except Asian tiger mosquitoes." We've also got what I'd consider a healthy predatory population -- tons of skinks, snakes, frogs, every bug imaginable (some have got to be predatory, right?) -- I know we've got wheel bugs because I accidentally killed a nymph yesterday before I realized it wasn't a squash bug nymph (similar body shape; wrong color...). Spiders everywhere. We live on a secluded private lane and I've never noticed the city spraying back here. But,.... we're getting eaten alive. Even my husband and kids are getting bitten this year, which is rare. Contrary to what I've heard on the news from "studies" I would disagree that concentrations above 15-20% deet are no more effective than the lower ones. If I wear the "regular" lower concentrations I might as well wear "here's dinner" signs. When I wear the 10-hour yucky oily stuff that's 95% deet it works like a charm. It's horrible, and who knows what it's doing to me, but at least I can step outside and check the garden. But, I did get in my shipment of essential oils -- I just still don't know how to mix the concoctions -- I've read the recipes posted but don't know what the base is. I'm even growing lots of catnip -- I don't yet have enough to take handfuls of the stuff and rub it on myself, but I'm working on it! So thanks again -- and I'll still welcome any recipes! mcaren...See MoreWhy can't California have mosquitoes?
Comments (26)There is no large general abatement "program" for mosquitos or any other bugs. Abatement is driven by conditions, which usually means there is standing water which could be a breeding ground. Abatement usually consists of removing the water. The only spraying program (other than agricultural spraying) I'm aware of was several years ago when an introduction of non-native species was creating problems. Even then, it was limited to areas where needed. California is subtropical, and very arid in comparison to anywhere east of the Rockies, as is most of the West. This has a significant effect on populations of pests who thrive on moisture (of course, we've got other critters....like scorpions!). The warm water of the Atlantic and the Gulf of Mexico (because of the Gulf Stream) causes the air blown inland towards the east coast, south and midwest to be very moist and much of the weather there is influenced by this (especially when it mixes with cold air coming from Canada...watch out!). However, west of the Rockies there is no influence on the climate of this warm, moist air. The Pacific is much colder than the Atlantic, so the air blowing inland contains far less moisture, and the dry, arid inland air (or air blown down from Alaska) keeps things dry. The most we get is thick fog ("June gloom") from the mix in spring and summer, as the ocean begins to warm up. So...we have far fewer rainstorms and less groundwater overall. Most of our water comes from the Sierra snowpack (thank you, Mr. Mulholland, and we're sorry about Mono lake). In the winter the Jet Stream shifts south, and winter storms come our way (usually, anyway), which is why it's our rainy season, and why some raging rivers dry up in the summer months. The further north you are, the more rain you'll have. Hence the greenery of coastal Washington and Orego (although inland Washington is much more arid than you'd expect, because some storms are blocked by the Cascade chain). So, because we are more arid, we have fewer pests that require standing water to breed. Nevertheless, have I mentioned the fleas? Or ants? Coastal regions are greatly influenced by the Pacific Ocean air, making these areas almost perfect, climate-wise. There are only a handful of places on earth with similar climates: the south of France and the coast of Chile. But you should not expect "tropical" here. The dry air greatly affects temperature, more so as you travel inland. There can be a 30 degree drop between daytime temps and nightime lows....See MoreMosquitoes!
Comments (27)Ladies, I would use the DEET, everthing I have read says it is safe. It is not an insecticide, rather it is supposed to make you "invisible" to the mosquitos and mask your scent. Below is a link to an article about it and youc an Google it too. I grew up in an area where many people were very much into "all natural" and "chemicals are evil." And I never questioned it. For years I had an innate aversion to anything "chemical." But as I've gotten older I've taken an interest in WHY people are so avoidant of chemicals and reading up on things it seems that in many cases of the fear is in our heads. The topic of mosquitos is one that REALLY upsets me. Here in the US people have the CHOICE of using chemicals to decrease their odds of bites. Plus we have easy access to information to help us decide for ourselves. But here is a statistic from 2005 about malaria: In areas of Africa with high malaria transmission, an estimated 990,000 people died of malaria in 1995 Â over 2700 deaths per day, or 2 deaths per minute. And from what I've read, the reason they still have malaria in places like Africa is because someone in the early 60's got hysterical about using DDT even thought there was ZERO EVIDENCE it hurt humans and the environmentalists took it up as a cause and got it's use stopped. Well, the malaria was pretty much gone in the US by then but the undeveloped countries suffer to this day. How very tragic to think ALL THESE DEATHS are avoidable and the result of UNFOUNDED fears by those who "think they know better." It makes me so angry my head wants to spin off my body when I think of all those people dying due to political correctness. So I will stop ranting and raving now... Here are a couple links about malaria if anyone cares: 9 most dangerous myths about pesticides: http://www.cgfi.org/materials/speeches/nine_myths.htm Malaria facts: http://www.cdc.gov/malaria/facts.htm Sorry. Mosquitoes vs. chemicals is a a topic that REALLY gets me going. Here in San Diego they are not bad but my Vet said heartworm IS on the rise -- he never used to see it now he sees a few more cases every year. Here is a link that might be useful: is deet dangerous?...See MoreWhat are you doing to fight back against mosquitoes?
Comments (37)I just tied on a some of Ragna's dryer sheets to my sandals and bra and went out to clean out my mosquito ridden pot ghetto that had been blown apart and was collecting little pieces of water. I have entirely too many 4", 1 gallon and broken cracked undamaged things.. Things were out of control. I was rousted out by another storm , but most are bagged and ready for a trip to the nursery or the recycling. We had a small tornado come through last summer and I have found pots a 100yds away. Embarrassing....See Morearcy_gw
