Odorous House Ants in Phoenix, AZ
Tapinoma sessile
Odorous house ants smell like rotten coconut when crushed and invade kitchens fast. Learn how Antidote Pest Solutions treats them.
Notes: From a Phoenix, AZ Exterminator
Appearance
Small and dark brown to black, odorous house ants measure about 1/8 inch. Their signature trait: a distinct rotten-coconut smell when crushed, which gives the species its name.
Harborage
These ants nest in shallow soil, under pavement, in wall voids, and near moisture sources like leaky pipes and A/C units — and they trail indoors in long lines searching for sugary food, especially after rain.
Are They Dangerous?
They don't sting or bite, but large colonies (which can include multiple queens) spread rapidly through a kitchen or pantry and contaminate food surfaces.
Treatment
Store-bought sprays often just split the colony further since these ants multiply through "budding." Antidote Pest Solutions treats the full colony network, not just the visible trail. Talk to one of Antidote Pest's Service Pro's to keep them out of your kitchen for good.
Prevention Tips
Fix leaky pipes, faucets, and irrigation, since colonies favor moist areas
Seal cracks around the foundation, windows, and utility lines
Clean up sweet spills and food debris quickly
Trim vegetation away from exterior walls
Store ripe fruit and sugary foods in sealed containers
Behavioral Notes
Odorous house ants release a smell often compared to rotten coconut when crushed, which is how they get their common name.
Colonies can have multiple queens and will 'bud' into new satellite nests when disturbed, which is why aggressive spraying often makes an infestation worse rather than better.

“I had ants in my home and couldn't figure out where they were coming from. I tried store bought poisons and traps and nothing worked. These guys came in and within one day, not a single ant to be found. It's been several weeks now. So thrilled to have found them when I did, especially since the weather is changing and stirring up all kinds of creepy crawlies. Thank you!!"
