The clinic has received the following samples in the past two weeks:
There are several kinds of small hairy or metallic bees that dig into the soil to nest, hence one common name, digger bees.
There are many species of ants that occur in lawns or along and under sidewalks. Most ants are beneficial and do not require control.
Tender perennials are attractive additions to the home landscape. Since they are not reliably winter hardy in Iowa, tender perennials must be planted outdoors each spring.
Arborvitae (Thuja spp.) trees and shrubs are appealing and reliable plants for the Iowa landscape with few significant pest or disease problems.
