HALEAKALA NATIONAL PARK, Maui (KHNL) - Haleakala National Park currently has high numbers of alien Western Yellowjacket wasps.
There is usually an increase during the summer months but park officials say this year is exceptional.
Areas where wasp numbers are extremely high include the base of Sliding Sands trail junction to Halemauu Trail. Wasps are also present at other locations within the park, although fewer in number.
Wasps are attracted to water, meat, sweets, perfume, cologne and sunscreen.
These insects may sting without warning and more than one may attack at the same time.
