Yellowjacket populations are on the increase in many parts of the country. These meat-eaters usually feast on caterpillars and flies early in the year. During late summer, their appetites switch from the high protein diet of insects to a carbohydrate diet. Thus, the appearance of yellowjackets at this time around trash bins, picnic baskets, and open soda cans. Yellow jackets attack with little provocation. Yellowjackets appear to be attracted to people wearing dark cloths or intense floral patterns, musk-based perfumes, and have bad breath (I guess it pays to brush your teeth). Fortunately, yellow jackets do not overwinter, as adults, so as cooler temperatures arrive this insect will become more lethargic.

Grubs continue to grow through active feeding of turfgrass root systems. Animals like raccoons, skunks, and armadillos will “peel” the turf back as they forage for grubs. For more information on grub control see:
