If they get too bad, grab a jug of insecticide. We use Talstar P with our 2nd and 3rd round lawn treatments now as an option. We use it to target mosquitoes, but there is a long list of other insects that it controls such as beetles, ticks, spiders, ants, etc. It doesn't specifically list "click beetle", but I would bet it would get rid of them. Nice thing about Talstar is you can spray it pretty much anywhere as long you follow the label. We spray landscape beds, patios, gutters, up in trees, anywhere that would be a hot spots for mosquitoes. We are getting pretty good reviews so far. Been seeing close to a month of control per treatment if we don't get a ton of rain.
