What is the Tarantula Handling Safety Checker?
The Tarantula Handling Safety Checker flags handling risk level such as venom or irritant hair for tarantulas. Many common household foods and products that are harmless to people are toxic to pets, and knowing the warning signs can make the difference in an emergency.
Tarantulas generally live 10-25 years when they are well looked after. They are an insectivore, so their nutritional needs shift with age, size and activity. Terrestrial species need more floor space than height, with substrate deep enough to burrow and no more than 1.5 times their leg span of climbing room, since a fall can rupture the abdomen. Keep an eye out for fall injury from over-tall enclosures, dehydration, failed molt. These are the conditions tarantulas are most commonly seen for.

How does the Tarantula Handling Safety Checker work?
The check is based on commonly documented toxic substances and warning signs for tarantulas, referenced against veterinary and poison-control sources. Treat the result as a well-founded estimate. Every tarantula is an individual, and your vet's judgement outranks any online tool.
What changes the answer
- The specific substance or food involved, and how much was consumed or encountered
- Your tarantula's size, smaller animals are affected by smaller amounts
- How quickly symptoms appear: which varies by substance
- Any existing health conditions that could increase risk
How do you use the Tarantula Handling Safety Checker?
- Answer "How long has the animal been in your home?"
- Answer "Is it eating normally and on schedule?"
- Answer "How does it react when you approach?"
- Pick your your handling experience (First time, Some, with guidance available, Confident and experienced)
- Answer "Is it mid-shed, molting or about to lay?"
- Press Calculate, then read the result alongside the sources listed below
If the result looks wrong, check your inputs before you worry. Entering weight in the wrong unit is easily the most common reason a figure looks off.

Before you rely on this
One number on one day is rarely the full picture. What matters more is the direction of travel: whether your tarantula is trending steadily, drifting, or changing suddenly. A sudden change is always worth a call to your vet, even when the individual figure still falls inside a normal range.
