What is the best way to keep bugs, specifically mosquitoes, out of a sukkah on Yom Tov? I've looked into various candles, tiki torches, etc., but they won't last through both days of Yom Tov.
I use mosquito barrier immediately prior to Sukkos and I have a mosquito free Sukkos.
we used dryer sheets taped to the inside of the walls. we labeled them annanei ha'kavod and they seemed to do a pretty good job keeping out both mosquitos and bees.
Here's some of the science behind it
We live on a farm, lots of bugs here... we use this in our Sukkah, as well as many other buildings.. : http://reliableexterminators.ca/index.php?main_page=product_info&products_id=151
Mosquito netting is effective, and is not a Chatzitzah between you and the Schach so long as it is hanging close to your body. (Don't support the Schach on the stuff...)
Though, that does give me a business idea... Moskito Netting that is Kosher for Schach - ie Made out of non-woven spun cotton... I wonder if it could work...
I was in a sukkah where the host had cut lemongrass growing in his garden, and spread it on the floor of the sukkah. I don't know if it was as effective as a citronella candle in discouraging mosquitoes. Also, lemongrass might only offgas the repellent for a certain number of hours, and be no more than a conversation piece after that.
There is no one thing you can do that will keeps bugs out of your sukkah. I wwould suggest a combination of all anti-bug technology
- off candles or other similar candles that make a smell bugs don't like
- torches (like candles but bigger.) probably best to have these by the entrance and not inside the sukkah
- a bug zapper. these work great but can be a little annoying because of the sound. better to keep nearby the sukkah but not in it
- lastly the distraction. the bugs really aren't there to "bug" you but because of the delicious dinner you are having. make them their own delicious dinner nearby but outside of the sukkah. For bugs sugar water works best. The sweet smells will lure them to the water and then they will drown in the water when they fly into it. There are also special bags and containers you can buy which are more effective. these have a hole at the top which allow the bugs in but not back out.
