Learn to identify areas that could be a source of water or would allow water to collect--as mosquitoes breed and lay eggs in non-moving water. Once this is understood, actions can be taken to eliminate those water sources and consider other practices to stay safe from mosquitoes.
The Controlling Mosquito Breeding Hotspots activity was designed to teach youth and adults about how mosquitoes can be a pest and how to stay safe with mosquitoes.
Participants identify areas that could be a source of water or would allow water to collect, as most mosquitoes breed and lay eggs in standing (nonmoving) water. By understanding where water collects, participants can then determine actions to help eliminate those water sources and also consider other practices to help stay safe from mosquitoes.
- Controlling Mosquito Hotspots Worksheet
- Controlling Mosquito Hotspots Directions and Answer Key Sheet
- Writing Instruments
The instructor can begin by sharing information about mosquitoes, including the facts listed below and how mosquitoes can be pests by biting humans and sometimes transmitting disease. Each participant can be given a worksheet and instructed to circle areas on the picture that could be a source of water or would allow water to collect.
Participants can write down ways to stay safe from mosquitoes beside the circled item or on the back of the worksheet. This activity can be completed in pairs or groups, with participants circling areas that collect water and discussing ways to stay safe. The instructor and participants should collaboratively review and discuss responses. The answer key on the back can help guide the review.
- Over 3,000 species of mosquitoes exist worldwide, with 200 documented species in the United States. A common type of mosquito found in Pennsylvania is the northern house mosquito.
- Adult mosquitoes have long legs with piercing-sucking mouthpieces. Mosquitoes need the blood of warm-blooded hosts for reproduction. Most mosquitoes breed and lay eggs in standing water.
- Mosquitoes can be a pest since they bite and can transmit disease. Mosquitoes can be carriers for West Nile virus (WNV). Mosquitoes become infected with WNV after biting birds that have WNV. An infected mosquito can then transmit WNV to animals and humans. Most people infected with WNV do not know they have it or only have mild symptoms. However, the more severe cases of WNV tend to affect those with weakened immune systems.
- Mosquitoes can also carry equine encephalitis (horses) and canine heartworm disease (dogs).
Mosquitoes, the insect that spreads the West Nile virus, can breed in puddles of water.
