Snow has not completely disappeared and you begin to assess the damage of the cold season on your entire property. Of course, you first check the structure of your house to make sure it survived well. Arm yourself with caulking to seal around pipes and vents where joints may have cracked during Winter. This will block out the potential invaders.
Voles, Shrews, and Moles
You see grass piles and trails on the lawn? This damage was done by voles under the snow cover. By the time you see this damage, let’s gamble that they are already back in their Summer habitat from where they migrated for the Winter season. Often they are accompanied by shrews, small insectivores with pointed snouts. Shrews move the earth to the surface in search of insect larvae. If you live near a stream or little creek, moles can complete the threesome and a single mole can do quite a lot of damage. These 3 species can be captured using multiple-catch traps.
Ants, spiders, sowbugs, and centipedes
The first pests to appear are usually ants and spiders, unless cluster flies or Asian ladybugs have spent the Winter in the attic or under the siding of the house. Brown field ants will have begun to work under stones as you encounter the first carpenter ants, a species that mates early in the season. Spiders are already moving as they hunt or stretch webs to capture insects and other arthropods that were hiding in the organic matter. Centipedes are usually active and useful in boosting the decay of organic matter.
In mid-May, solitary bees will be observed, especially in the sunny embankments of sandy soils. They are harmless and are not attracted to humans at all. They dig their nests in the ground to build a cell in which they will deposit food for their offspring after having laid there.
Black field ants
"Mound ants" will only appear after the first couple of mowings of your lawn. There is no doubt that when the blade of the lawnmower touches the top of the mound, it will trigger panic in the colony and ants will run everywhere for a little while.
Whatever discoveries you make in your Spring yardwork, it is important to identify the ennemy you deal with prior to taking action.
