Types of insects

Mosquitoes

We investigate and control mosquitoes, which can transmit diseases like West Nile virus. We conduct mosquito surveillance and treat mosquito habitats to reduce the spread of disease. We treat stagnant swimming pools and standing water sites, where mosquitoes often breed. We also help residents learn how to protect themselves and their homes from mosquito infestations.

Wasp and hornet nests

We investigate and treat low-hanging wasp and hornet nests in curbside trees within reach. We do not treat nests attached to residential properties. Please contact us for more information if you are concerned about a stinging insect nest.

We do not have a service for honeybee swarms. Do not disturb them — they will fly away within the next few hours. You may contact a beekeeper if you’re concerned.

Sewer roaches

We investigate and treat roach infestations inside sewers only.

We do not treat for roaches, fleas, bedbugs, or other insects inside homes. Please contact us for more information that may be useful in controlling these pests.
