Evanston Now reader Anna Renee Ross this morning sent in a photo of one of the odd phenomenons of summer in the city — the appearance of the burrows of Cicada Killer Wasps along the edge of lots where grass meets the city sidewalk.

Ross says she noticed four of the burrows in front of just one house on the 1600 block of Ashland Avenue today. They seem to pop up all over the city this time of year, as the hum of the cicada fills the summer air.

Various experts say the large wasps, which can be nearly two inches long, rarely sting or bite humans — but who wants to test that?

Ag extension services say that the right amount of lime and fertilizer on a lawn and frequent watering can eliminate the wasp infestations.

But perhaps the best news is that while the wasps generally appear the last week of July, they’re usually gone by the middle of August, after they’ve helped cut down on the cicada population.
