There are yellow jackets in my yard, how do I control them?
Rate This FAQ
Social wasps consist of three types --Queen, Workers and males. The Queen over-winters in protected sites. In the spring she builds a small nest and lays eggs, and as they hatch the colony increases and the nest becomes larger. Adult wasps capture insects to feed the young during the summer, and in the fall other sweet foods are eaten. All workers die prior to winter and the nest is not reused. Yellow jackets usually build their nests below ground, and they are very aggressive in defending their nests. Unlike honey bees these wasps can sting multiple times. Aerosol sprays and traps are effective controls, if the nests are treated at night when workers are in the nest.
European paper wasps resemble yellow jackets but are not attracted to yellowjacket traps.

- I have a scarlett red maple. It's about 8 years old and last year the leaves didn't get very big. This year, it hasn't even began to bloom yet although, It has tiny buds. I noticed that the bark in some places peels off very easily. Under the bark, it looks like there may be some black flecks (maybe bug feces). I only noticed one little red colored bug under where I peeled the bark. I don't see any other bugs anywhere, even at the base. Do you think it could have a disease or bugs? I am going to put some fertilizer steaks around it and pour some Bayer Advanced tree and shrub insect control around the base of the tree. Is it too late to spary it?
