I have not seen too many of them here in Central IL this year and that is unusual. However the farmers are still getting some of their crops out of the fields so there is still time to get a swarm! And as for taking care of them I stick with the vacuum method, I try not to squish them because of the stink they put off. Just another example of bringing in a foreign species to try to maintain another one. God has checks and balances but people think that they could do a better job than Him.....gesh!
