Invasive Japanese beetles are back in Denver and Colorado — and they are hungry

They are baaaaaaaack.

Yup, it is official, Japanese beetles (Popillia japonica) have returned to infest Colorado gardens — albeit maybe a little bit later than typical, some gardeners have found.

The shiny, round, invasive pests generally exhibit up in June and stick all around all summer season — what’s even worse, the most reputable strategy for receiving rid of them is waking up at the crack of dawn and plucking them off your vegetation a single by a single (ew) and then drowning them in a bucket of water.

Central Denver resident Carol LaRoque gets rid of her bugs in a a little unique way — by feeding them to her neighbor’s chickens, who rapidly gobble them up (the animals are observed in numerous sources as an superb and effective pure beetle repellent). She mentioned she’s plucked only about a dozen beetles off her roses so much, but is selected this is just the starting.

“It does look like they emerged later on this yr,” she observed. “I did not compose down the date last yr, but it seemed like by some time in late June, we experienced already had them final 12 months.”

Colorado gardeners have been speedy to increase the alarm about the return of the leaf- and flower-hungry fiends. Colorado State University’s Grasp Gardeners have been posting about them on social media given that June 29, with a handful of beneficial truth sheets about controlling them and preserving them out (The Denver Article has its very own guideline right here), but they have so far been fewer in variety.

The late starting to beetle period in some parts may be thanks to the dry winter season Colorado professional, according to Richard Levy, a scientific information manager at the Denver Botanic Gardens, the place Japanese beetles are just now beginning to present up.

Japanese beetles lay their eggs in turf grass, wherever they expend 10 months in the larval phase underground. Frozen, barren soil uninsulated by snow for extensive intervals of time can lead to later on adult beetle emergence from the ground, and that may be what some regions are observing now.

Despite the fact that they surface to be leaving the rose bushes by itself in favor of the hollyhocks (for now), Denver Botanic Gardens communications director Erin Bird remembers backyard volunteers having to scoop off hoards of beetles by this time in many years past.
