Females can start laying eggs as soon as you see adults. Once the adult flies are discovered, management decisions should be made. Adult flies are tan with red eyes and a tiny 2-3mm-long (up to a one-eighth of an inch). Males have characteristic dark spots on their wings that can easily be seen with a magnifying glass. Adults live for up to 2 weeks, and females can lay up to 300 eggs. Development from egg to adult can occur in as little as eight days, and 10 or more generations may occur within a season.
1. Control grubs in the lawn to eliminate moles and voles? Fiction.
A mole’s diet consist mostly of earthworms. This does not mean they won’t eat a grub, but grubs are not their preferred diet. Although mole tunnels can be a nuisance in a lawn setting, most landscape plants are not bothered. Moles generally elude traps, so it may be best to accept them as part of the ecosystem of your yard.
Voles are herbivores. They do tend to eat bark during the winter months, so a protective trunk wrap may help in these cases.
