Fleas are annoyingly fast to reproduce and can carry blood-born diseases. All it takes to cause a flea problem is one guest or customer with a pair of unwanted stowaways on their clothes. Fleas can nest, feed, and breed either indoors or out, living off of organic debris and preferring to attach themselves to people an animals. This means a severe nuisance, especially for businesses. A flea problem is a guaranteed way to lose business. Meanwhile, for homes, your poor pets will suffer the brunt of the assault. A combination of human- and pet-safe treatments will kill these pests and prevent their eggs from spawning.
