Improve the health and performance of plants in your yard or garden naturally with this beneficial insect house! Gentle solitary bees are capable of pollinating up to 20 times the amount of flowers as honey bees. Hollow plant stems and pre-drilled wood blocks in these houses provide these power pollinators with the perfect place to lay their eggs, which ensures that you have these helpers around for years to come! A shutter chamber and mesh chamber can serve as shelter for predatory insects such as ladybugs and lacewings who eat harmful plant pests such as aphids. A beneficial insect house is a great tool for anyone wanting to improve plant health and performance without the use of harmful chemicals.
