Ultraman Ace
In Ultraman Ace, there is an episode about an ant monster that sucks the blood of women with type O blood. The heroine Nan Yuko happens to have type O blood, and then Beidou Chuji was imprisoned in an underground dungeon by the spaceman who created the ant monster. Ace couldn't escape to send Ultra's signature, and Zoffie came to save him. However, Ace was locked up for too long and the red light came on. Zoffie gave Ace a plug-in artifact that could replenish the energy of a transformation when worn on his hand. Go to the ground for 2V2, and then you know the ending.
There is an episode of Ultraman Taro about space ants. The ZAT team found that pesticides were ineffective, so they replaced them with boiled water/fire breath/spray guns. In the end, the ants merged into monsters and went to the west. ~
