Be vigilant for inside dwellers such as bed bugs, cockroaches, spiders and commensal rodents such as house mice, roof rats and Norway rats.
Spring brings out most pests because the ground begins to thaw. Pests that you can expect in the spring are occasional invaders (centipedes, millipedes, pill bugs, sow bugs, earwigs), ants, spiders, large and small flies, bed bugs, stored product pests and rodents. Spring is also the time of year when carpenter ant and termite colonies begin to swarm.
Summer will bring a continuation of the pests that come out in the spring, but you will also need to be aware of carpenter bees, wasps, yellow jackets, hornets, fleas and ticks. The biggest threat stems from mosquitoes, which will start in late May and run through the summer months and into the fall. Also certain areas in the Northeast will see an increase in cluster fly activity from August into September.
The fall is when insects and rodents want to come in from the outside to find harborage from fall's cooler weather. Residential and commercial customers can expect to see an increase in commensal rodent activity, occasional invaders (including crickets, box elder bugs, earwigs), spiders and ants. There is also a possibility of "late" carpenter and termite swarms. Bed bugs are a concern for any season of the year.
