Mosquitos are a problem here. The Asian Tiger Mosquito showed up here in 1999. The Authorities said it wasn't here yet. It stunned one back then and kept it intact in a small jar in the refrigerator and tried to tell the Dept Of Natural Recources and the local University that I had one, but no one seemed interested.
So, naturally, a YEAR later the local newspaper headlined "Asian Tiger Mosquitoes Found In Maryland". Yeah, I knew that.
Anyway, I have been fighting them ever since. The little bastards are active in daytime and are hard to detect on your skin. I happen to be good at detecting them on me, so I have probably killed more of them than the average victim.
This year, I am fighting back. I'm trapping them. Well, not the adult females, the offspring. They lay their eggs in water. There is a bacteria (Bacillus thuringiensis) that kills the larvae. It comes in various forms, but I like the small Bt doughnuts of it that you just drop in standing water.
I set out 5 pots of water with the Bt around the yard last month. I set one pot without it. When I see larvae in the untreated pot, I know the the females are laying their eggs in the treated water too. I dump the untreated water pot every 2 days. The treated water pots never have live larvae!
I found old black plastic pots that fit a gallon food baggie perfectly. The dark pot makes the water look good to the female mosquito The orange landscaping flag is so that I don't lose track of where they are. The Bt has to be re-added once each month.
Getting the first few generations killed makes a BIG difference. Already, I can go outside and find only a couple flitting around me and I swat them against my shirt very fast. Fewer and fewer of them. They don't travel far, so most of them here are from here.
Two years ago, I could hardly go to the mailbox without a bite. This year, NONE!
