Tree Check Sonic Wave Tree Decay Detector is a breakthrough technology in sonic wave timers that will become an international standard in the pre-climb safety check, tree risk assessment and urban forestry inventories. Tree Check is designed for arborists and urban foresters as a low cost, simple to use, reliable field tool to detect the likely presence of significant decay, cavity or cracks in standing trees. Used properly it can "see inside the tree" revealing areas of concealed severe deterioration that undiscovered could result in tree structural failure or resultant property damage or personal injury.

Mosquito control can be a profitable service add-on. Everyone agrees mosquitoes are an annoying and potentially dangerous pest in the summer months. That would seem to present a big business opportunity for anyone in the business of getting rid of mosquitoes. Lawn and landscape companies that have begun offering mosquito control services are taking advantage of that broad-based demand.

Not only can mosquitoes carry diseases that afflict humans, but they also can transmit several diseases and parasites that dogs and horses are very susceptible to. These include dog heart worms, eastern equine encephalitis and West Nile virus.

There are about 200 different species of mosquitoes in the United States, which live in specific habitats, exhibit unique behaviors and bite different types of animals.

Different species of mosquitoes prefer different types of standing water in which to lay their eggs. The presence of beneficial predators such as fish and dragonfly nymphs in permanent ponds, lakes and streams help keep these bodies of water relatively free of mosquito larvae. However, portions of marshes, swamps, clogged ditches and temporary pools and puddles are all prolific mosquito breeding sites.

Every once in a while it pays to stop and think for a minute. It is human nature to see an insect and want to get rid of it. We should rethink that. There are a lot of insects that are harmless. More importantly there are some that help us. Our scouts have been bringing in good guys regularly, including ladybug larvae (fig. 1), a pupating ladybug (fig. 2), and an assassin bug nymph. These insects feed on other insects. Sometimes they do wander into our homes and become a nuisance, but when they are outside, they are beneficial to the gardener. The bottom line is to take a minute to think before you squash or spray an insect. Sometimes they are the good guys.
