Late spring delivers everything gardeners crave: fresh mulch, booming tomato plants, longer evenings, and lawns that suddenly grow like they drank an energy drink overnight. Unfortunately, the season also flips the “open” sign for one of the most aggressive pest cycles of the year. The moment temperatures consistently hover above 60 degrees, insects begin breeding, feeding, and expanding territory at an incredible pace. A single overlooked issue in May can explode into a full backyard invasion by July. Garden centers across America see the same pattern every year because homeowners often notice pests only after damage spreads everywhere.
The real trouble starts quietly and almost invisibly. Tiny aphids gather under leaves while mosquito larvae wiggle around standing water after spring rainstorms. Ticks climb tall grass waiting for pets and people to brush past, while grubs start chewing beneath lawns before brown patches appear later in summer. Many gardeners focus heavily on planting season but completely miss the pest activity brewing underneath the surface. Late spring acts like a starting gun for insects that thrive during hot weather, and the cycle gains speed fast once temperatures rise.
