Why spring is the most important season for bugs

Happy First Day of Spring!

Spring is the season of hope and new beginnings, as the earth seems to come alive again. It’s a time to do a deep clean of your house, get your lawnmower out of storage, dust off your grill and patio furniture, plan your garden and watch color return to the landscape.

Spring means rejuvenation in the insect world as well. A key part of the life cycle for most insects happens in spring, and this season can set the stage for their activity the rest of the year.

Wasps, hornets, yellowjackets

In spring, the wasp, hornet and yellowjacket queens that have spent the winter hibernating start to emerge and establish new nests. Wasps are not affected as much by spring precipitation since they typically build their nests in sheltered locations and high up off the ground. A warm and dry spring is ideal for yellowjacket colonies to get started.

What you can do: Use our TrapStik® for Wasps, W·H·Y® Trap for Wasps, Hornets & Yellowjackets, or Reusable Yellowjacket Trap to catch the queens before they build nests. Any queen caught now means one less nest later on in the summer.

Japanese beetles

Spring is when damage to turfgrass happens, by Japanese beetle grubs feeding on roots. The time to trap them isn’t until summer, when they emerge as adults and start flying.

What you can do: Treat your lawn with a combination of Milky Spore and Beneficial Nematodes in spring. Be prepared with our Japanese & Oriental Beetle Trap for when adults emerge in summer.


Spiders become more active and resume mating in the spring, and any eggs that were deposited in the fall will hatch. Above-average temperatures in spring create the ideal conditions for spiders to thrive. It also means more insects on which they can feed.

What you can do: Set our Spider Traps in various places where spiders are typically found indoors: against a wall or baseboard, under toe kicks, around doorways, behind toilets, behind or under furniture, and inside basements or crawl spaces.

Pantry moths

Dormant pantry moth eggs hatch, and the life cycle that had slowed down in fall and winter starts to pick back up again.

What you can do: It’s important to use our Pantry & Birdseed Moth Trap to catch the adults before they can mate and perpetuate the life cycle.

Stink bugs

Stink bugs that have been hiding out in your home will start to leave the house. Before you get encouraged by that, you should know that once outdoors, they intend to mate and lay eggs. This is when stink bugs are most vulnerable, and when you can have the greatest impact by trapping them. 

What you can do: Hang our Stink Bug Trap outdoors in a deciduous tree – this is where stink bugs frequently go to mate once they leave the house.

Black flies

Spring runoff means the rivers and streams have fast-moving water – which is ideal for black flies to mate.

What you can do: Use our TrapStik® for Biting Flies outdoors and wear our GoClip® on the back of your shirt collar if you are doing any activities outdoors – especially  if you are around any rivers or streams.


To survive the winter months, most ticks find shelter in leaf litter and are dormant until spring. Juvenile ticks, or nymphs, are dormant during the winter months and become active in the spring. Adult females also lay their eggs at this time. A warm, humid spring has the potential to create a tick outbreak in early summer instead of late summer because it gives newly hatched eggs a greater chance of surviving.

What you can do: Use our Mosquito GoClip® when you’re outdoors near any areas with tall grasses or brush. Since ticks will often jump on to you near your lower body, attach the GoClip® to your waistband, shorts pocket or shoelace.
