I live ini Oakland CA next to a maple tree (not a true box elder tree) but I have the bugs. Last year, hundreds were mating in the house and their population exploded. Seems it's the right time of year to take action this time.
The maple tree is extremely tall (4 stories, so hard to drench) and I haven't seen the bugs on or near it -- they could be hiding anywhere. When it was the end of their season last year, they all seemed to want to crawl up.
I think I saw a suggestion of a lightbulb above a dish of soapy water, but would that work just in general anywhere outdoors around the building? Or should I try that in the attic crawlspace?
And would a soap like Dr. Bronner's castille soap be less harmful to other bugs and plants?
