I saw this tip in "Country" magazine years ago and use it every year to trap yellow jackets and hornets. I have this one hanging in the grapevine. The yellow jackets like the apple juice better than the grapes. Lures them right in and they can't get out.
Because mosquitoes are attracted to the CO2 we breathe out, I started looking for ideas that used CO2 as the bait for the mosquito trap. I did think of dry ice but it does dissipate fairly quickly.
I read about web worms in today's newspaper. Then looked at the neighbor's tree. Yup, the season has arrived. Among other things, the most natural treatment is to rip a hole in the web so natural predators can get in there and finish the job.
I've been looking for the ant poison that is a liquid in a small bottle - price is $2.00 (Liquid Bait Ant Killer). Finally found a store that wasn't sold out.
