Prevention Tips

Waterbugs congregate outdoors in moist, shady hiding places where food and water is readily available. They are also found in woodpiles, mulch, lawns and hollow trees. Waterbugs will randomly enter the home seeking food or water or when weather conditions are extremely wet and cold.

Indoors, infestations can be reduced with good sanitation, eliminating food sources and keeping food in sealed containers, repairing water leaks, and sealing cracks and crevices.

Outdoors, keeping mulch levels to a minimum next to the house, eliminating standing water, trimming shrubs around the house, sealing exterior entry points such as cracks and crevices with a waterproof silicone caulking, repairing broken screens, sealing openings around water pipes, and eliminating wood piles next to the house will all help in keeping these pests from entering your home. Treatment of harborage areas with outdoor insecticides labeled for this use can help reduce waterbug infestations before they seek shelter inside the home.
