Why the Surge Now?

The combination of heat, humidity, and ripening gardens creates the perfect storm for pest pressure:

• Drying soil pushes ants and spiders indoors for moisture.

• Summer gardens and trees attract flying insects like wasps and mosquitoes.

• Cooler nights ahead drive spiders and rodents to seek shelter early.
