Kissing Bugs Control & Removal Guide
(Assassin bug, Cone-nosed bug, Triatomine bug)*Triatoma infestans* / Triatoma spp.
How They Get In
- Old building cracks: adobe wall cracks, thatched roof gaps, wood structure joints, and under furniture are their primary harborage.
- Yard and outbuildings: wood piles, rock piles, abandoned structures, and animal enclosures (chicken coops, dog houses, rabbit hutches) are common breeding sites.
- Light attraction: adults fly to lights and enter through open doors/windows at night.
- Lumber and building material transport: hidden in materials moved from infested areas to new locations.
How to Get Rid of Them
- Seal Indoor Cracks: Use sealant and cement to fill all wall cracks and holes; repair damaged walls and roofs. Pay special attention to cracks in bedroom walls and bed frame joints — kissing bugs emerge from these at night to feed. Install screens on windows and doors to prevent adult entry.;
- Secure Sleeping Areas: Move beds away from walls; keep bedding from touching the floor. Use insecticide-treated bed nets for long-term protection. Check walls and bed frame crevices for bugs before sleep.;
- Yard Environmental Management: Clear wood piles and debris from around the house; store firewood on elevated platforms away from the home. Regularly clean animal enclosures (chicken coops, dog houses, rabbit hutches); treat if kissing bugs are found. Trim tree branches and vines touching the house.;
- Indoor Residual Spraying: Apply pyrethroid-based residual surface treatment to wall cracks, roof spaces, door/window frames, and bedroom walls. In endemic areas, professional application of long-lasting residual insecticides to all indoor walls is recommended.;
- Personal Protection and Medical Care: When living or traveling in endemic areas, use bed nets (preferably insecticide-treated). If you suspect a kissing bug bite, do NOT scratch the bite area (to avoid rubbing parasite-laden feces into the wound) and seek prompt medical attention for serological testing. Early treatment of Chagas disease is more effective; chronic-phase treatment is difficult, making early diagnosis crucial.
Prevention & Follow-Up
Seal all cracks and gaps in walls with caulk or cement. Move beds away from walls and keep bedding from touching the floor. Use insecticide-treated bed nets. Clear woodpiles and debris away from the house. Clean animal pens and shelters regularly.
